Ive posted about this problem before, but we are getting no where with the problem and Im getting conflicting advice from Plumbers.
To briefly describe our problem:
We have a Megaflow CL250 Cylinder sited in our cellar (its an old victorian House) The cyclinder has good incoming pressure of 5 Bar (plus). This was achieved at great expense by moling a MDPE Main under the garden, in order to get rid of the old Lead Main.
The Main is t'eed as it enters the property in the cellar. 1 way goes to a PRV currently set to 3 bar and feeds the cold supply in the house and the other T is the main supply to the Megaflow. (with a large bore plastic pipe of 28mm.) This supply then goes through the factory supplied PRV that comes with the Megaflow (with the built in strainer.) Which says it is factory set to 3 Bar. Without fitting a dial gauge onto the pipe run from the PRV to the cylinder its impossible to say what the incoming mains pressure is, but it should be 3 bar, reduced from the incoming pressure of 5 bar shouldnt it?
The outlet from the top of the Megaflow is the standard 22mm.
The resulting pressure in the whole of the house is poor to say the least. We had a plumber measure the Hot Water flow rate at 13 litres per minute (which is poor is it not?) The balanced cold water flow rate is identical.
The Kitchen Hot Water flow rate (which is a short run from the cylinder in the cellar to the kitchen above) is 13 litres per minute and the outlet in the bathroom on the next floor above this is also 13 litres per minute (which kills any theory that long pipe runs with bends etc are causing a loss in pressure.)
Can anyone advise of any other possible causes? Im really pulling my hair out on this one. Thanks for any help.
