too much cold pressure for shower balance

[ae106400]

me and a friend installed a bathroom but the cold was from the mains and the pressure too much for a good balance in the shower.Its a thermo mixer from aldi he bought . Anyway we put two service valves at the begining of the run for the appliances (hot and cold) and ive now had to put another service valve on the cold after the wc and basin but before the shower.this service valve is almost shut off to equal the pressure.
Whats the deal with pressure reducing valves? i had a look at some pic on the net and they seem massive.i need something better than a service valve to stop the pressure surely.

aldi?? Didn't realise they are plumbing merchants. Did you get a free tin of beans with it?

Hot and cold must be balanced ie both off gravity supply from cold storage tank

you can get a pressure-reducing valve, not very cheap. Just install it in the cold water supply pipe to the shower. I had one on a seldom-used guest-room shower, and it used to seize shut, but maybe they're OK in regular use. I have an idea they are in the £30/£50 range.

Proper installation in the first place would not need this to be fitted

 

[JohnD]

indeed so.

ha ha ha ha. yet more numpties who think plumbing is easy. love it.

only reduce the flow by nipping back valve ,pressure remains constant. Thats why we had to go to and still do at great expense to college which is reflected in our invoices.

Do you mean by nipping back the valve or by nipping a back valve? Which valve?

And, of course, you did remember to put in a double check valve on the cold water supply I hope?

Because if you did you wasted your money. Only needed a single check valve

come on giblets any one who buys their shower from a supermarket its BOUND to know water regs

As above
