Evening. A friend has a two storey house which has the kitchen and living room on the first floor and a bathroom and bedrooms on the ground floor.
He's also had a two storey extension added which now houses a further bedroom with en suite bathroom and a utility room which backs onto it, both on the ground floor with a lounge directly above.
The water/heating consists of a system boiler in the kitchen, cold water tank f and e in the loft and a HW cylinder on the first floor landing.
The problem is that he that the cold water pressure in the extension is awful. So bad in fact that it wont fill the washing machine properly and the machine shows an error message "insufficient pressure"!
The cold water supply to all of the extension is rubbish and yet the hot is fine. Toilet takes forever to fill and is amazingly quiet !!!
There are no problems with the hot or cold in all other (original) parts of the house, including the original downstairs bathroom.
My mate seems to recall that the original plumber (2 years ago when the extension was added) saying that the cold water pressure in the extension would never be as good as the hot water...but he can't remember the reason.
To my mind, the cold water pressure in the extension should be as good, if not better than the other draw off points upstairs, given that, I assume the supply was tee'd off the existing supply pipes and would therefore originate from the cold water tank, and the draw off points in the extension are even further away, gravity wise, from the CW storage tank.
My only thought at the moment is that there is some sort of restriction or partial blockage on the cold feed supply to the extension....and finding that could be a nightmare, given that all the pipes are in the stud walls and under floors etc.
Any help/advice greatly appreciated
