Outside TAP / construction /

[Useroftheforce]

Chaps - I want to put an outside tap on the front of my terrace house. There is a small garden there, so not into the street. Inside the house seems pretty obvious. pipework under the floor to the foundations. Through the foundations and underground to the tap site seems more complex. It's that part I am interested canvassing replies on the appropriate design.

I do know that I will need a drain point, check valve and isolation valve, all that is easy to site in the cellar before the run travels (lagged) under the lounge floorboards.

Therafter I guess a 22mm sleeve through the wall and then??

And then what? Elbow up the wall to a tap, with exterior pipe lagged.

Or, if your burying a section, it's supposed to be a minimum of 750mm below ground. For ease of installation, and for it's current purpose, I'd be inclined to run plastic pipework (wrapped in foam insulation) in the ground with concrete slabs or similar on top to protect it from a wayward spade. Just remember to drain it when the weather gets cold, especially if it's not 750mm down, and in any case since the tap end will be above ground level.

you can use one of these

saves having any copper pipe outside.
i think they look alot neater than a wall plate and the pipe going to it.

Agrred, seco, but I'm guessing that this will make the tap height too low for the op. In any case, the bit saying "underground to the tap site" suggests it may not be on the immediate wall.

does sound abit confusing.

then like you say external pipe to the wall plate/tap.

Yes - I wasn't clear enough. I need to check but I think the DPC (being an old house) has been injected about 2" above ground level and I think the floor boards are 2" above that. I can't raise the hole through the wall internally since that would involve an obvious pipe inside the bay window of the lounge. I am not sure whether to site the tap on the immidate exterior wall or run it further and site it on the inside wall that marks the front of the property. But I guess the house wall would be more simple.

What does one lag the outside of the pipe with?
I would use the push over foam for the inside.

Does your main come in under the front(small) garden Dig a hole +connect to it with an underground stopcock /liner and lid. Then have a galvanised standpipe/checkvalve/tap free standing from Drain Center

Sadly not - it arrives from the neighbour at the back of the house in the cellar, from their cellar.

push-over foam will be ok on the outside.
