I'm installing a new basin/mixer in my downstairs cloakroom (where the old 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 ? Tony

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.

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.....

It is, isn't it? If you need instructions on how to fit one feel free to ask.

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 know it all amateur.

We were somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "Doctor Drivel" <killef...@invalid.invalid> saying something like:

Cor Maxie! You know all these things. Fantastic! What a man. What a man. So, Maxie have you stopped swearing to people in the street yet?
