getting a pulsation from the solution pipe, rang smart mart at hydramaster, and he told me its the header pump, (think thats what he called it, got six brass bolts on it, take em off and clean the plastic thingymagingies out, took em off but couldn't get the placky things oot. didn't want to force em. what do i do once the brass bolts are out?
ps... just taking the bolts out and cleaning them cured it a little bit but its back again now, and martins off air for the weekend. could do with having a go on sunday.
