Hi. I'm about to replace the T90xr with the T90z. I've turned off the cold water to the bathrooms, as I don't have individual isolating switches on all appliances. When I go open the inlet valve, there's still a lot of pressure inside. I presume there's only a small amount of water in there anyway? Thanks.

STOP!!!!!
The supply for the shower will be fed directly from your attic tank. There should be a valve in the attic. Make sure your electrics are off at fuse board

I can't see that valve. I presume turning off the mains and draining all taps will do the job?

Yes when the large tank in the attic is empty you should be safe. Be prepared for airlocks when refilling though

Just drain using the cold tap on the bath, which might minimise air locks, rather than using the hot taps as well.

Thanks. What do you do about airlocks?

hoppway

Won't turning off the isolating valve in the hot press be enough? Thanks.

hoppway

Thanks. What do you do about airlocks anyway?

Have you got an airlock on the hot or cold?

Hi again. I think I've found the valve, if it's a right-angle Comap in the attic. It's locked to the left, and I can't turn it right either. I presume gentle force won't do any harm?

STOP !!! it might start leaking if you force it

Get a wine bottle cork, pull up your sleeve, block the hole in the tank (where the valve is connected ) from the inside

Unless its a 3/4 pipe and the wine cork goes straight down the pipe

And then there'll be more than airlocks to worry about!!

Sounds more like they are afraid to apply any pressure at all. Just turn the thing.

Used to do that on the odd one that had no valve. Not with corks though.

Or if was a qualpex pipe, sometimes cut it with cutter, and immediately lift above tank top level, and fit valve.

There's a rubber plug that can be bought and it fits both 1/2 and 3/4 tank fittings. It's very handy

Thanks.

Yeah.

Good to know, thanks.
