Water pressure on mains shower

ovalfan1

Iv a mains shower and I'd like to increase the water pressure what's the best way to do it any help would be appreciated.

You cant, its due to the flow valve restricting the water to heat, you will notice a better flow rate on the cold setting than when you turn it to the hotter settings.

In my last home the shower-set up was (a) cold water directly from mains and (b) hot from the storage-tank heated by the gas (Baxi) boiler combined through a mixer-tap. It was silent and sufficient (I've never understood why people want to pummel their bodies with hard jets of water).

Is it possible to do this combination with mains cold + water from a boiler heated by a combination of solid-fuel range and electric immersion heater when range not in use during warmer weather? The property does not have mains gas and I don't want to use bottles.

I also have a shower/water pressure issue:I have installed a new gravity fed shower on the first floor. The water pressure is a joke, so bad that it is genuinely un-useable, the flow of water wouldnt rinse the soap off. The bedroom has a very high ceiling so bottom of cold water tank is about 5 feet above the shower head. Hot water tank is on the ground floor - so about 13 feet below the shower head. Pressure in bathroom taps is fine. The shower works off a (probably too cheap) Sonas Reece thermostatic shower valve with minimum operating pressure of 1 bar (am I right in thinking this valve is only suitable for a pumped system in Ireland?). I don't need a power shower, just something adequate for a proper wash. I am wondering whether a better quality shower valve that has operates under low water pressure would do the job. I see there are some valves that have an operating pressure range from 0.2 bar to 5 bar. Don't want to throw good money after bad, and find that a better spec of shower valve makes no difference. Don't want to rip out the shower and mess up my tiles in order to install a Triton shower or similar. Advice welcome. (also, any recommendations for a cheap and effective power shower should I need one). Thanks

Mains fed electric shower
I have a triton t80z and I have been told my mains pressure is too high. I fitted a pressure reducer and non return valve but am unsure what is the average bar pressure at which to set the reducer. Anyone out there Know?

The min mains pressure is 1.5 Bar. So try somewhere between 2 and 3.

I was recently told by a plumbr that you can't plumb an electric shower direct from the mains, that you have to supply from the storage tank.

Mains feed can be used for an electric shower that has no internal pump. Use tank gravity supply to a pumped shower.
See here the Model asked about is Mains Fed.

Its unusual to have a problem with high mains pressure, the T80Z can operate with a maximum mains (static) pressure of 10 Bar which most mains would never reach. Operationally it would just mean keeping the temperature control (flow) switch at a lower setting to maintain the same flow/temperature than when operating at the more usual mains pressure of 3.5 to 1.5 bar. Maybe the lower pressure results in a quieter shower. The very big advantage in having higher mains pressures is that the shower flow stabilisation valve will maintain a much better constant flow if a tap or whatever is opened. My mains is allways 3.8 to 2.8 bar and turning on a downstairs tap or toilet flush etc has no noticeable effect on the showering temperature.

Some undulating areas, esp rural can have high pressure on the mains not reduced, in the valley, in order to get up the next hill. South Tipp is an example.

Thats understandable allright, I suppose 10 bar, say 100 meters or ~~ 330 feet isnt a huge head/height, as a matter of interest I wonder what is the OP's pressure.

Water John

I think the highest was 16 bar.

There are parts of Dublin where people can only use their mains fed shower between 11 & 7am due to the bad pressure.

Water John

Any thing over 5 or 6 bar is tops needed. After that its too high.
