Mixer tap with lo pressure hot and hi pressure cold ?
TonyB
basin had two separate taps).
Now as the cold is fed by the rising main, and the hot by the tank in the
loft I have a pressure imbalance to cope with.
I believe this requires a pressure reducer valve on the cold feed.
I also require each feed to have a single check valve to prevent cross flow
between hot water and rising main.
Then I also wanted to add a service valve to each feed so I can turn off the
water to the basin.
The pipes come through the wall from the kitchen behind kitchen cabinets,
and I don't have a lot of room to install all this stuff below the basin.
Unfortunately the mixer tap doesn't have built in service valves.
Are there any clever fittings that combine say the single check valve with a
service valve, or a pressure reducer with a check valve and service valve ?

Are you sure? If the "mixer" doesn't mix the waters until they exit
the spout then you don't do you? Check the design of your mixer tap.

I did a similar thing in the kitchen with a posh lever arm mixer. Only to
discover it was really intended for high pressure only. As most of these
things are these days. So have you actually tried yours yet? I ended up
adding a pump to the hot rather than reducing the cold flow.

Are you sure you need this?

Where flow is a problem as likely with the hot, best to use full bore
valves.

valves. I think the water mixes inside the mixer not in the spout.
Thanks

I hope not, as the hot flows pretty well, and drives mixer taps in the
kitchen with no problem.

According to the tap manufacturer, apparently I do ? I guess it depends on
the mixer design.

OK. The tank is 2 floors up in the loft, so flow rate isn't bad.....

Yep. A pump for one tap. Amazing.

I would never be so dumb as to fit a pump on one tap, so do not need your
instructions.

You obviously don't know anything about 'designer' mixers which are only
for high pressure supplies, then. But if you ask nicely I'll help you out.

Very sad - I offer to help you and get an insult instead. Typical of a
