I tested the small Grundfos condensate pump yesterday that I have ran hose for.
It's a long run of hose (around 5m upwards from pump with a good gravity drop thereafter to catch my kitchen sink waste pipe- around 10m from the head- just within acceptable limits). I have the hose simply terminating into a plastic hose fitting, going straight into 1.5" plastic waste pipe.
All seems generally fine except after the pump stops pumping, air obviously works back into the clear plastic condensate hose and you can see water draining up and down (as though a partial syphon effect before things settile (pipe/tubing emptying/draining. I think I'm going to hear some noise at my kitchen sink from the set-up but this isn't presently a worry.
I can't imagine this causing any great issue but am wondering if it is avoidable? Would a water trap before the condensate goes into the 1.5" pipe help?
Thanks
