Hi all,
I recently fitted a pump to boost the shower pressure in the house. The plumbing is all flexible pipe and all cold feeds are fed off the same 22mm ring. Taps, toilets, showers and bath, both upstairs and down. Don't know if this is normal, but it is normal in Donegal, North West Ireland!
All works fine except that when the toilet cisterns are near full the pump pulsates on and off till they are full. I am assuming this is caused by the pressure switch being activated / deactivated as the flow drops to a dribble in the cistern. However, after researching on this site, it may be 'hammering' and the pump has flow switches???
The pump is made by / called Techflow. I am planning on replacing it with a larger pump as two new en-suites are being installed. Will a non return valve or a negative head pump sort this?
The pump is located below the hot water cylinder with its own dedicated and thermostatic feeds.
