Hi,

Is there a 4 way T piece at for 15mm pipes. Well it would not be T more like a cross. I know I can do it with 2 T pieces in sequence ... just asking.

Cheers
Charles

very very unlikely i doubt there has ever been enough demand for several hundred thousand to pay for the machining costs

Like a Yorkshire YP 50 you mean.

Why would you need such a fitting.

Sorry BA

Piping under my bathroom is probably 1" size. Hot is gravity fed, cold is mains pressure.

There is one hand basin fed by a pair of "I guess" 1/2" pipes, new basin will not be in exactly the same position. A bidet that will be removed fed by a pair of metric pipes. Toilet cistern fed from inside the room where the mains valve is ... do not want to feed new cistern from there.

I want to tap once in the cold supply and feed:
1 line more or less straight up to the new handbasin
1 line (around 2 - 2.5 meters round the underside of the room to) and up to new cistern.

OK 1 T piece does the above.

==================

I would like to connect with a ball valve in the middle Cold feed to gravity Hot and feed cold up the hot system. Hence 3 lines out from one feed. If the hot water tank is drained I need a few seconds of reverse feed to make it flow again. Please don't tell me to fix the plumbing ... beyond me.

So far I got away with the reverse feed as the hand basin has two single taps (connect them and it works). Next hand basin will have (famous last words) a single mixer tap and I intend to fit a single check valve on the hot (necessary ?)

Anyhow ... all the bathroom bits have not arrived, I am running out of time this year to do the job so I can see me looking for a plumber in the new year.

Cheers
Charles

Some taps have check valve built in otherwise they should be fitted, when you have mains cold and tank hot for example, or there's a risk of backflow.

Bidets should be tank fed only.

Thanks


It is mains fed. May or may not have a check valve on the cold feed but it is getting removed anyway.

If you can avoid the YP 50 do so, as 1 will equal a box of normal tees.

If should really use solder fittings but I will still need compression bits in a small space. (i.e. from pipes to floor ... I have plenty of vertical space if I take the pipe downwards and then back up the way which I don't want to do).

For a compression fitting to be safe do I need a minimum length of pipe between fittings? Compression joints with very short pieces of pipe between them look a bit too wobbly to me.

Provided the pipe is right in the fitting it should be ok.

Use a jointing compound on the olive (Fernox is good)
