Hi ,
I am new to the forum and would really appreciate some help with a job we are currently doing.
I have installed a new bathroom(where an existing was already) for a client and during the works they have got their plumber in to supply a pump to boost the supply to the hot and cold in the house.
The hot water cylinder and cold tank are on the first floor the same as the new bathroom. The plumber has fitted a negative head pump as there was not enough height on the tank to get a positive head pump to kick in for the shower head.
Before the work they had an electric shower and poor flow to the other taps etc for hot water.
The problem I now have is that when they try and start the shower or any hot water on the first floor in the morning or periods where it has not been used for a while they need to flush a downstairs toilet or run the kitchen sink also on the ground floor before the pump will kick in with hot water, although the cold works fine all the time.
The hot water downstairs and everywhere else then runs with a lot of splurging of air for a while and eventually is clear and all works fine until it is left for a period of time again and they have to go through the whole process again.
The plumber fitted a 2.5 bar stuart turner negative head pump, this is basically running the whole house bar a cold main to the kitchen sink.
I am not sure how air is getting back into the system once it has been cleared, could there be a problem with the way the pump is connected to the vent pipe on the cylinder? or is there a problem with the pump being upstairs and feeding a floor below as well? and is this size pump suitable for this type of work?
Any advice would be greatly appreciated ,
Many thanks
Marcus
