My current pump is a Grunfos 15-50 x 18 and its on its way out, it was noisy anyway but after stripping it down and removing numerous insect carcasses and a rusting screw from the blades it is really grumbling now.
The only issue i have is that grunfos do not do this model anymore so can anyone tell me which one i will need to replace it with, the system is a y plan with a Myson economist boiler.
