Mains Water Pressure

michaels

MY mains water is fairly low pressure and poor volume.

I am having an extension and would like to have enough water pressure and volume to run a shower at the same time as a bath.

Currently the mains does not supply enough volume to support this so it looks like I will need a tank and booster pump. However if there was a way of improving the mains volume then this would not be necessary.

Is it possible to have the pipe from the road stopcock to the house replaced with a larger bore in order to get more mains volume? Any ideas on cost for this?

You can do that - you own and are responsible for the pipe from the point where it enters your land. If there were a leak, it would be you that had to get it fixed - not the water company.

Larger pipe will increase flow rate, but not pressure.

Have you had your local water authority out to check your water supply up to your stop !!!! in the street?

What does fairly low pressure mean? As G4Y says what is the actual pressure being deliverd by the water supply company to your premises? Also as he says flow rate and pressure are not interchangeable terms.

Is your extension in build at present? If so you should consult your builders plumber then who can recommend the best solution for your particular circumstances.

it must be easier to install a tank in the loft, and a whole house pump if required.

It might be that the valve from the mains supply pipe to you house needs opening further. Our pressure dropped and it turned out to be this. The water board man simply cleaned out the inspection hole and turned the valve open.

The water board are only required to provide 1 Bar of pressure, if its lower than that then you have some recourse against them but if it isn't, then it's a much more laborious task to get sorted.

15l/min, haven't checked the pressure. Accumulators seem to fix this but at large expense and also they take up space hence wanting to investigate a better mains flow as well.

Would you like a practical solution to this?

In the absence of one from you, I would suggest closing the stop tap on the rising main that should be found just below the cold water header tank. Presuming the cold water tap on the bath is not direct and that the shower is electric, this should work although it would be a bit of a hassle closing and reopening it every time.

I asked a very specific question in a very specific way for a very specific reason. I did not ask you to interrupt and I did not ask you to be rude either. I need to find out if the OP is prepared to answer some questions in order to be able to give him some help. If he isn't there is no point in trying.

Your suggestions are pants because they are based on uninformed speculation of what plumbing system the OP has got in his house.

PS Just luuurve your own thread on insulation of HWCs but I am not going to post on it as you will probably only be rude again. Have a nice evening.
