Trivial tee valve

mfizz · 3 Nov 2020

I think I'm missing the trick here. I want to convert this into an outlet that I can connect a hose to as well as the toilet cistern.

I'm sure I need a tee valve but they all seem to be either 2 compression ends 1 screw on with a single lever. I want to be able to turn the hose off as well and still maintain supply to the cistern.
What am I missing here. I don't want a network of pipes.

I have a flexi pipe going into the cistern which I would like keep.

What sort of hose do you want to fit? Washing machine, garden hose or something else?

You need a washing machine tee and a short piece of copper pipe.
New Tee goes in place of current flexi hose/isolator combo (use the nut and olive already there to attach it).
Then short piece of copper using one nut from new tee.
You'll be left with a spare nut and olive that you then use to reattach the flexi/isolator combo.
You'll need a 3/4 cap for the tee for when the hose is not attached (to prevent accidental opening of the valve).
Beware, you may have modify/remove the blue handle that comes with the washing machine tee as it will likely bind against the cap and/or hose spigot when they are attached. A couple of extra washers in the cap/hose spigot can probably assist with negating this.

Why would you want to fit another outlet to a fitting that's underneath a toilet? Wouldn't be a douche would it?

Good shout @Madrab
@mfizz don't do that!

@Madrab - I already have a douche fitted but that's connected directly to the cistern. The toilet is very close to the front door so want to use it as an outlet for the pressure washer, rather than running the pipe from the outside to the front.

@oldbuffer - It is a garden hose that will go into the pressure washer.

@dilalio just to confirm that I'll be able to isolate hose without stopping flow into the cistern

Can I use this?

I thought that was forbidden (if the cistern is mains fed)?

It is.

Really? How so? Doesn't bother me it's off anyway, it was already there. Will remove it if I can get an easy way of attaching my pressure washer

Cold mains outlet (douche) within reach of sewerage can result in contamination of the potable water supply and contravenes WRAS.

In a nutshell... Risk of drinking water that has $hit in it.
