I have a booster pump for the house hot water system. It has worked extremely well for the last 4 years supplying hot pressured water to the whole house. In the last few week the pump comes on every 5 mins for 5 secs when there is no water demand. I have looked for water leaks everywhere and everything is bone dry!
There is obviously a leak somewhere (unless pump is knackered after 4 years - it does get a lot of use), can anyone please tell me how I can possibly trace such a small flow of water, as it may well be hidden behind partitions walls etc.
The pump is a salamander ESP 120. I cannot find how I would adjust any flow switch. However, having just looked at the installation and guidance it looks like it was set for negative head and not a positive. It is a positive head with the tank in loft well about water outlets. So I reconfigured it for positive flow. In the installation guide it does warn about hunting when used with a negative pressure head, but is cushioned by the pressure vessel.
Hopefully this will do the trick and thanks for responding so quickly. I can't find in any of their brochures where I might adjust a flow switch. If you have any further ideas or thoughts I'd appreciate it.
