I'd be grateful if someone could please advise on this.
I would like to flush a couple of radiators using a pressurised sludge remover. Do I have to remove the radiators before doing so - or can I simply apply the cleaning product through the radiator's air vents?
Hi,
I would like to check if my Grundfos UPS 15-50 is working ok. I have read many post related to this pump but none explained how to check or even clean a UPS 15-50 - Can anyone please advise?
