increasing water pressure

[daveeg]

Hi Gang

Going to try and give as much info as possible as i know you guys have the best knowledge on the net.

Right to start with been to see a client who has low mains water pressure. I have tested pressure at kitchen sink and getting 3mbar still and about 12 liters per minute.

They have 2 big storage tanks in the attic that feed vented 150 liter hot water cylinder and cold supplies to bathrooms.

There is a basin and kitchen on ground level, a hot water cylinder, bathroom and shower room on 1st level. The boiler is on ground level and gravity fed, header tank in attic.

Tested the flow rate on basin on 1st floor and only got 6 ltr per min
The shower is pumped so not bad there.

The client is just wanting good pressure at all outlets what is the best way to go

Thanks All

There is huge storage tanks in the attic

Its only main to kitchen sink they rest is fed off the tanks

I did look at pumps but was confused

Will the cylinder be big enough to cope with the pump; 150 liters? What about it pumping over the vent?

pump in the loft feeding an unvented cylinder, the only thing I would keep off the pump is the toilets and the kitchen sink.

could you advice a cylinder? should i increase the size? not sure how i could run separate supplies to the toilets and pump the rest as they will be on the same supply pipe? do you mean keep the main at the kitchen sink?

Thanks Pal

vaillant unistor for the cylinder, try the heatrae sadia site for sizing , I would feed the toilets off the tank in the loft and the kitchen sink off the mains for drinking water.

cool...thanks

I will be installing a vaillant ecotec 618 boiler as well, there is 12 rads in the house will this be sufficient? Basically make it a sealed system from the boiler and gravity on the cylinder feed?

Does the pump have a problem with toilets?

It sounds like a blockage somewhere.
