Outside tap help please

[Mike-H]

I am trying to fit a tap to an outside wall. All of the taps that I have seen are angled to take a feed from an internal source, which I appreciate is normal. However, the existing source runs up the wall already from the ground (do not know why, it’s not my house). Are there any external garden taps suitable for an upward feed like this?

You need a wallplate elbow.

this is available with or without one

The check valve stops the water syphoning back up into the tap and contaminating the supply.

For instance your filling your pond, there's a water cut, and bingo the water that was in your pond is now flying back up the hose into Thames Waters pipes.

I'm not sure how likely that is - and you don't need a check valve tap in every situation, but I always tend to put one on.

every outside tap must have a check valve.

It should have a double check valve fitted and an isolating valve. If it's a new installation they should be fitted inside the building. If you're replacing an existing one you can fit a tap with an integral doublecheck valve I believe.
But in view of this

Are you sure it's a water pipe not a gas pipe?

You don't need a check valve tap at all, they don't comply with water regs. Should be an isolator and double check valve inside, and the tap outside

depends if its a new install or a repair on an old install.

surely if we change a tap today it needs to be to todays regs, therefore needing a double check valve, or am i too used to doing the gas regs where work needs to be to todays regs
