Hi tappy, water quality has rust particles in expansion tank. Gate valve is on primary return and it is fully open. If it was sludge I'd have expected that expansion tank water to be really dirty? On a combined feed and expansion I can't see that the pump can influence a pump over so you could give it a try by running it on top speed which could be enough to shift the sludge deposit if that's what it is. One more, if the pump was changed 4 years ago could the new pump have been fitted the wrong way round? Would it be worth throwing another new pump at it? I'll turn up pump to speed 3 when home later. I'll also check pump flow direction,good thinking. I have spare pump but I'll try your ideas first and see what happens. Thanks tappy

One other wee point; if it’s a perforated coil in the cylinder, the F&E tank will constantly overflow, day & night!!
