shower valve
A pressure-balanced valve provides water at nearly constant temperature to a shower or bathtub, despite pressure fluctuations in either the hot or cold supply lines.
If, for example, someone flushes a toilet while the shower is in use, the fixture suddenly draws a significant amount of cold water from the common supply line, causing a pressure drop. In the absence of a compensating mechanism, the relatively higher pressure in the hot water supply line will cause the shower temperature to rise just as suddenly, possibly reaching an uncomfortable or even dangerous level. Conversely, if someone opens a hot water faucet elsewhere, the relatively higher pressure in the cold water supply line will cause the shower temperature to drop suddenly. This is described in US patent 3674048.The pressure-balanced shower valve compensates for changes in water pressure. It has a diaphragm or piston inside that reacts to relative changes in either hot or cold water pressure to maintain balanced pressure. As water pressure drops on one supply line, the valve reduces the pressure in the other supply line to match. A side effect of this is that the pressure and flow at the shower head or tub spigot will drop twice as much as if only one supply line had been affected, but without a large temperature change. There are ball bearings in the valves to regulate forces.
The use of pressure-balanced valves can prevent scalding injuries, in particular to the elderly, the infirm, to children and infants. Based on that, some municipalities require by building codes to have it installed.

Hi,

When I turn on my shower, one shower pump automatically comes on for both cold and hot, so I'm assuming that I have a twin impeller pump installed somewhere in the flat.
But I've noticed that the hot water always dominates so that I can never achieve warm, luke warm or even cold water...

I am considering fitting a Thermostatic shower valve in a bathroom to one of my customers. They have a multi point gas water heater.
My question is, will it cope with the demand of the shower?

I know it's a long shot but does anyone recognise this shower valve?
It was fitted approximately 6 years ago.
A customer has 2 of them and there are problems with both of the temp controls. One of them is really stiff and almost imposible to operate with wet hands. I have managed to free it...

Hello everyone,
I have a power shower pump fitted in my airing cupboard that feeds my shower only. Some times at night it runs of its own accord when no other taps or appliances are on. Can anyone help with this strange and annoying problem?!!
Many thanks.

Can anyone tell me what shower valve this is. I have a problem with it as
it will not turn off on the first attempt. After several attempts at closing the valve it eventually shuts off if left for 2 or 3 minutes.
I want to repair it or replace it if I can find a replacement that uses...

I've got a 3/4" triple control thermostatic shower valve to install. Does it have to be piped up in 22mm pipe, it will be running off a combi boiler as the old pipework in the bathroom is 15mm. Also the pipework taht will be feeding the shower head does that have to be in 22mm pipe. Thanks.

I have a Beaumont Sequential Shower Valve and the tap is leaking. I live in a hard water area and guess it is probably clogged up with limescale. Can anyone tell me how the valve/tap comes apart? Many thanks
