my water pressure is rubbish

This will depend on System that you currently have; 1. If a COMBI Boiler then there is not alot you can do to increase flow/pressure, has you cannot add pumos to this system. 2. If a Gravity Fed system then you have a couple of options; a) Convert all cold water feeds to Cold Mains Water and fit a pump on the Hot Water side of the system after the Hot Water Cylinder. b) Put both Hot and Cold water supplies into a pump. c) Fit a Unvented Hot Water Cylinder System like a Megaflow which is then all Mains Cold Water Fed. 3. Other reasons for poor flow could be; a) Old Iron Pipes that are clogged up, restricting flow b) Head of pressure from Cold Water Storage Tank not sufficient c) If a COMBI Boiler, either poor Mains Cold Pressure coming into building or COMBI not poerful enough to produce required water levels. I would really suggest that you get a Plumber out to give you your options and costs for each type of solution. Bill Pipe Dreams Plumbing Services Bournemouth

do you have a combi boiler or hot water tank/emersion tank system ? if you have the later then a pump will help with speed.
