Fitting a shower pump

[paddy2]

Hello,

My shower has v poor pressure/performance. It's a standard central heating type with the cold feed coming from the header tank and the hot coming out of the top of the cylinder. I've heard about these 1.5 bar shower pumps you can buy, would one of these make a big difference? Are they difficult to fit for an enthusaistic DIYer?! Do you need to switch them on and off, or are they "load sensing" and kick in when the water starts flowing? I'm always a bit dubious when we start mixing water with 'lectric.........

Thanks.

Indeed you can buy shower pumps that boost the flow. It is often better sited in the airing cupboard next to the HW cylinder and should be powered by a 3amp fused spur ( although 'Salamander' pumps come supplied with 3 amp plug fitted ).

The cold supply needs to be a new feed tapped from the cold water storage tank and into the pump.

The hot can be fed from a number of ways depending on what make of pump you buy. Surrey or Sussex flanges are the better ways to get a uniques feed from the hot water cylinder. Some makes allow you to tap off from the domestic HW supply providing it is the first draw off.

You also have to ensure that the pipework is sized correctly to and from the pump.
