bought a red dragpn x return pump. Had a varios 4s before, this was completely silent. the only reason I replaced it was because the low water sensor was gone, and then I thought I'd buy the best. it works very well, but it has a faint whirring sound, or if there is a gear that is grinding a little.
feil med pumpa, eller er den ikke lydløs?
