WATER PRESSURE FOR POWER SHOWER

[tazkb]

I WOULD LIKE TO FIT A POWER SHOWER BUT I HAVE MAINS WATER PRESSURE FOR THE COLD AND GRAVITY FEED FOR THE HOT HOW CAN I GET AROUND THIS?
IS THERE A WAY OF EQUALISING THE WATER PRESSURE FEEDS TO THE SHOWER?
THANKS

you can use a pressure reducing valve, available from any good plumbers merchant

Can you tell us why it won't work ? We're all learning & listening here.

Sorry missed that. The PEV isn't designed for a negative and varying pressure load , and the pump expects a low impedance source without any time delays. Upshot is it all oscillates (unless you're very lucky!). Neeasty!

If you use a single ended pump on the hot (low pressure) and use a mixer which will cope with a fair pressure mismatch, it usually works out ok, but no manufacturer would be keen to gaurantee it would work! Depends on the mains pressure too.

Thanks i asked a few plumbers and they agreed so i have fitted a mixer designed for my plumbing system and will try it he did say if its a bit crappy fit a pressure reducing valve to sort it out

You are better off if you can get the cold feed from the cold storage tank for equal pressure.Trouble free & safer regarding getting burnt from hot water if someone turn on the cold taps.
