Hi again,
Replaced faulty (dead) pump with equivalent from Wickes - new pump has a 3-position speed setting. Original unit had an adjuster with no markings... instructions with new pump say what adjuster is but otherwise are as much use as a chocolate teapot.
When running the pump, it can be heard as a rushing noise all over the house. I bled the pump before switching it on - have I missed something? I have a Parkray solid fuel room heater connecting to a h/w cylinder in the downstairs airing cupboard, the pump is fitted at the lowest point of the circuit.
What is the purpose of the speed adjuster - apart from the obvious of course... ?
