"brought this pump as I had enough listening to old pump for two years churning away in cupboard and now all I hear is tinnitus. Have to say was not easy getting old one off as it was giving a good fight with pump pliers and gentle tapping with a squirt of WD40, resorted to buying new pliers and good quality which done the job no problem. Very good and like everyone else I'm sure, you will be back every day to confirm its still on. Would recommend without hesitation."
"Brought to replace a very old pump that had become very noisey. This one replaced it perfectly, very easy to fit, all seals required were included. It auto bleeds itself of air and is SO QUIET that I have to keep checking that it is working!! It also automatically varies its speed so it and the heating system should always be working in its most efficient way. To early to say about reliability but Grundfos stuff is normally very good."
"Our old pump failed & within a couple of hours I had purchased this off the shelf & fitted as a direct replacement for the old one - no pipework changes needed! Seems to be a top quality item & is so very, very quiet compared to the old one. Not sure how I can rate reliability after two days...ask me in a decade!"
