Scope
What this checklist covers
The preparation ground these prompts walk through.
- Separating watering, cleaning and filling into what each one really needs
- Choosing a position by walking the routes rather than by wall convenience
- The hose itself, where it is stored and what it drags across on the way
- Splash, run-off and what happens to the surface directly beneath a tap
- Cold spells, periods away and who is responsible for shutting things down
- Questions about supply, pressure and connections for a qualified plumber
Audience
Who this checklist is for
- Owners with no outdoor water who carry cans out through the kitchen
- Households planning planting or a terrace where watering will become routine
- Owners whose existing outdoor tap sits in the wrong place for how they garden
- Anyone preparing notes before a qualified plumber is approached
Timing
When to use it
- Recording what water outside would actually be used for through the year
- Testing a proposed tap position by walking the routes it would serve
- Deciding where the hose lives and what it would be dragged across
- Noting what the surface beneath a tap has to tolerate in constant wet
- Listing the supply and connection questions to raise with a qualified plumber
Limits
When it is not sufficient
This is general planning preparation. These situations need a qualified professional, and often the relevant authority.
- Deciding how a supply is taken outside or what fittings a connection needs
- Judging whether existing pipework or an existing outdoor tap is sound
- Working out how a tap or its pipework should be protected in cold conditions
- Settling what local requirements apply to outdoor water or hose connections
- Designing where splash or run-off from a tap should be taken away to
The checklist

1.What the water outside is genuinely for
Watering, washing and filling place quite different demands on a tap. Separating them is what turns a vague wish into a useful brief.
Write down whether you mainly fill watering cans or run a hose, since a can needs height and a clear stance while a hose needs somewhere sensible to lie.
The two uses pull a tap in opposite directions, and a position chosen for one often turns out to be awkward for the other.
Record what actually gets washed outside, whether that is boots, tools, a bike, a dog or the paving itself, and where each of those things happens now.
Washing tends to be the use that decides the position, because it happens in one fixed spot while watering moves around the plot.
Note anything that would need filling, such as a pond, a water butt, a paddling pool or containers on a terrace, and how far each sits from the house.
Filling is slow and unattended, so it matters whether the tap can be left running somewhere you can hear or see it.
Consider whether planned planting or containers would change how much watering the plot needs, and record that as a reason for the tap rather than an afterthought.
Container planting and newly established beds need far more attention than mature ground, and that demand often arrives after the taps are settled.
Decide whether anyone would drink from the outdoor tap or fill a pet bowl there, and raise that with the plumber rather than assuming either way.
What an outdoor tap may be used for and what has to be in place at a hose connection are matters for a qualified plumber, and requirements may vary locally.
Note who in the household does the watering and whether they could manage a full can from the tap position you have in mind.
A tap that only works for the strongest person in the house quietly changes who looks after the garden, which is rarely the intention.
2.Where a tap would earn its position
Taps are usually placed where a pipe is convenient. It is worth testing the position against the walks it is supposed to save.
Walk from the proposed tap position to each part of the plot you would water, carrying something heavy, and note where the walk becomes unreasonable.
Distance on a plan feels nothing like distance with a full can, and this walk is the single most useful test an owner can carry out.
Record which corner of the plot is furthest from any water and what currently happens there, since that is usually where planting struggles.
The dry corner is often blamed on soil or aspect when the real cause is simply that nobody is willing to carry water that far.
Consider whether one position genuinely serves the whole plot or whether a second point elsewhere would change how the space is used, and note it as a question.
Asking about a second position early is far easier than asking after the surfaces are laid, even if the answer turns out to be no.
Note whether a hose from the proposed position would have to cross the seating or dining area, and picture doing that while the space is in use.
A hose dragged across a terrace is the reason many outdoor taps end up unused, and it is entirely predictable at planning stage.
Write down whether the tap would sit beside a door, a window that opens outwards, or a bin store, and whether any of those would be blocked when it is in use.
Taps need standing room in front of them, and the space they occupy in use is much larger than the fitting itself suggests.
Consider whether the tap needs to reach a parking space or a drive, and note whether the hose would then lie across a route people walk.
Vehicle washing is a use that dictates position and one owners often remember only once the tap is fixed somewhere else entirely.
3.The hose and where it lives between uses
The hose is the part of the arrangement people actually handle, and it is the part almost never discussed while a tap is being planned.
Decide where the hose lives when it is not in use, and check that the place you have in mind is genuinely reachable rather than behind everything else.
A hose stored somewhere awkward is a hose that stays where it was dropped, which is how a tidy plot ends up with a coil across the path.
Note what the hose would drag across on its way out, particularly bed edges, low planting and any surface that marks or scratches easily.
Hoses flatten edging planting and scuff soft surfaces, and both effects appear early enough to be worth designing around.
Consider which corner or upstand the hose would catch on when pulled, since that is where planting gets torn out and pots get knocked over.
Hoses always find the pinch point, and moving a container or softening a corner is easy while the layout is still on paper.
Write down whether you would use a reel or simply coil the hose, and be honest about which the household would maintain rather than which sounds tidier.
A reel needs a fixing position, standing room and someone willing to wind it, and none of those should be assumed.
Note whether water left in the hose matters to you, such as when the first flush comes out warm or sits in the sun on a terrace all afternoon.
Standing water in a hose affects both comfort and what it can sensibly be used for, and it is a normal thing to raise with a plumber.
Record whether your existing hose connections drip in use, and where that water currently goes, since a leaking connection lives directly above the surface.
Fittings, connections and anything that joins a hose to a supply should be specified and fitted by a qualified plumber.
4.The ground directly beneath the tap
A tap is a small fitting with a large wet patch under it, and the surface beneath is usually chosen without that in mind.
Note that the ground under a tap is wet far more often than anywhere else, and decide what surface you would be content to have staying damp there.
Constantly wet surfaces colonise, stain and behave differently underfoot, which is why the material under a tap deserves its own decision.
Watch where water runs when you empty a bucket in the proposed position, and write down where it ends up rather than assuming it disappears.
How water is taken away from any outdoor surface is a drainage design matter for a qualified professional, and requirements may vary locally.
Record whether the ground at the proposed position falls towards the house, a wall or a doorway, and raise it as a question before any position is fixed.
Whether water would run towards a building is for a qualified professional to establish; never plan a wet position against a wall on your own judgement.
Consider what happens to the mud and grit that washes off boots and tools there, and whether it would be carried indoors on the way back through.
A washing point beside the back door is convenient until everything rinsed off it is walked straight into the house on the next trip.
Note whether you would be standing on that wet surface while filling a can, and what that surface is like underfoot when it is soaked or cold.
How a surface behaves when wet or frozen is for the manufacturer and a qualified professional to advise on, not something to judge from a dry sample.
Write down whether marks running down the wall below a tap would bother you, and note the finish that wall currently has.
Splash marks and staining below an outdoor tap are common and permanent enough that owners with a paler wall would rather know first.
5.Cold spells and periods away from the property
Outdoor water is easy in mild conditions and unforgiving in cold ones. These are the questions to have answered before, not after.
Ask a qualified plumber what should happen to the outdoor supply in cold conditions and who is responsible for doing it, then write the answer down.
Protection of outdoor pipework and taps in cold weather is for a qualified plumber to specify; do not rely on general guidance for your particular arrangement.
Record where you would isolate the outdoor supply from inside the building, and check that whoever is at home could actually reach it.
The point of isolation is only useful if the household knows where it is, and that knowledge is normally lost within a change of occupancy.
Note whether the property is left empty for long stretches, and who would notice if something outside were dripping or running unattended.
Unattended water is the failure with the largest consequences, and an owner can at least state the pattern of occupancy up front.
Consider who waters when the household is away, and whether that person would have access to the tap and know how it works.
Holiday watering usually falls to a neighbour or relative, and access arrangements affect where a tap sensibly goes.
Write down whether anything outdoors is currently labelled, and note what you would want labelled at the end of the work so nobody has to guess.
Labels are trivial to ask for during the work and impossible to add reliably afterwards once everything is buried or boxed in.
Note any existing outdoor tap, standpipe or capped pipe you have seen at the property, without opening or operating anything you do not understand.
Existing outdoor pipework should be assessed by a qualified plumber before it is reused, extended or reopened.
7.Leaks, upkeep and the records you keep
An outdoor tap is a small thing that can cause a large amount of damage quietly, so the closing questions are about noticing and record keeping.
Consider whether you would notice a slow drip in the proposed position, or whether it sits somewhere nobody looks between one season and the next.
Position governs detection, and a tap tucked behind a store or a shrub is one that can run unnoticed for a very long time.
Decide who looks over the tap and its connections when watering starts up again, and what a quick look would actually cover.
A short written routine survives changes in who does the gardening far better than an intention that lives in one person's head.
Write down what you would do if the tap started leaking, including who you would contact and where you would turn the water off.
Repairs, alterations and anything involving pipework must be carried out by a qualified plumber, not attempted as a temporary fix.
Ask what may and may not be used to clean the surface under the tap, since the area stays damp and tends to be the first place anything grows.
Cleaning products and methods should follow what the surface manufacturer states; where growth keeps returning, ask a qualified professional what is causing it.
Note what you would want recorded at the end of the work, including where any pipe runs and where the outdoor supply is isolated.
The record is worth more than the tap in the long run, particularly to whoever next digs a hole or plans a structure on that side of the plot.
Set down the cold-weather routine and the isolation point in plain terms, so the next household is not working it out for the first time during a freeze.
This is the knowledge that vanishes when a property changes hands, and it tends to be wanted on the coldest night rather than on a convenient afternoon.
Preparation
Documents and information to gather
Having these to hand usually makes the first conversation shorter and more useful.
- A sketch of the plot with proposed tap positions and the areas each would serve
- Notes from walking each watering route while carrying a full can
- Photographs of any existing outdoor tap, standpipe or capped pipe you have found
- Any paperwork you hold about previous plumbing work at the property
- A note of where the water can be isolated inside the building
- Information from the relevant water undertaking about restrictions in your area
Records
Decisions to record before work begins
Write these down in your own words, with the date, so everyone is working from the same version.
- Whether the tap is mainly for filling cans, running a hose or washing things
- Which position is proposed and which parts of the plot it is expected to serve
- Where the hose lives between uses and what it would be dragged across
- What surface will sit beneath the tap and stay damp because of it
- Who isolates the outdoor supply in cold conditions and where they do it
- Whether provision should be left for automatic watering later
Professional review
Questions to discuss with qualified professionals
Bring these to the relevant qualified professional, supplier or authority. Requirements vary by project and location.
- Given where we water and wash, where would you expect an outdoor tap to be most useful here?
- What would running this tap do to water pressure elsewhere in the building?
- What has to be in place where a hose connects to the supply at this property?
- What should happen to the outdoor supply in cold conditions, and who does it?
- Where would water from washing and splash go from this position, and who designs that?
- What would be involved in leaving provision for watering equipment we might add later?
- Which parts of this have to be agreed with the surface contractor before anything is laid?
- What has to be confirmed with the local authority or the water undertaking before we proceed?
Blind spots
Commonly overlooked items
- A hose that has to be dragged straight across the seating area to reach the beds
- The permanently damp patch of surface directly beneath the tap
- Mud rinsed off boots and then walked indoors on the way back through
- Nobody in the household knowing where the outdoor supply is isolated
- The corner of the plot nothing gets watered in because it is simply too far
- Splash marks running down a pale wall below the fitting
- A slow drip in a position where nobody looks from one season to the next
What this checklist does not do
- This checklist does not decide how water is taken outside, what fittings are used, or how any connection is made — those are matters for a qualified plumber.
- Protection of outdoor pipework in cold conditions must be specified for your property rather than assumed from general guidance.
- Where splash and run-off go from a wet position is a drainage design question for a qualified professional, particularly close to a building.
- Restrictions and requirements for outdoor water use vary; confirm what applies with your local authority and the relevant water undertaking.
