water pressure

[cedarhills16]

Dear Kibkomers,

Appreciate some advice? We have a a gravity feed water system in our place, plastic pipes etc. However, we have a poor pressure water flow, taking a shower is a joke! I have cleaned Tap Filters, Shower Head etc etc, to rid the pipes of limescale. I was wondering if anyone could suggest a solution that may help to get a better pressure at the shower to deliver a proper flow of water. I don't want to fit pumps into the pipeline in case it damages the pipework etc.

I am intending to get Mehmet to come give me a quote for Bathroom refurbishment as advised by the kind Kibkomers that responded to me previous post.

Just need to get sorted out please

Check that the outlet from the top tank isn't restricted by something in the tank, or a faulty isolation valve on the outlet.

you need a flow control unit that will give you pressure when you need it but to do this you will have to change a few things if you contact us we could sort or give you a quote http://www.braceybuilders.com

Has it always been that way? Or is the low pressure just a recent development?

Hi CatalkoyChris,

Always been that way!

Pump it. Only way unless you increase head and pipe size.

Our pressure is actually now higher from the mains than from our pump system. Up to 3 bar mains, more than enough, our pump is set to 2 bar.

Incidentally, if you want maximum protection for your system if you do go for a pumped option, choose a pressure relief valve carefully. You will probably want no more than 2 bar for a roof mounted PRV, but best if you can put one at ground level by the pump, and needs to be set at just about pump output pressure.

Be careful what is fitted, I have seen many 6 bars PRV's on hot water system, and on the roof where the pump pressure is lower. These are way too high, and a tank is likely to 'relieve' (rupture!) before the PRV.

It takes 10m of head of water to get 1bar of pressure at outlet. A pumped system is the way to go. Worries about it damaging pipework are strange. If a pumped system running at around 2bar damages your pipework then it needs ripping out. Isolation valves at outlets have very small holes and block up easily.
