I replaced my Grundfos with this Teral from zheilwane i think 2 years ago. Happy with the recommendation so far. I feel it works just as well as Grundfos without the premier pricing.

My Grundfos died on me on year 3-4, after dismantling, found out it was fuse problem and could have been repaired for around few hundred if DIY.

My Teral works equally well , I have it connected to a power switch where I off it when no one is using. Theres a leak in the house and the motor do get turn on and off every 15 mins if I forget to off the switch.

but who or where to fix? Called Groundfos , already will have base service charge.
next time i will diy if happen.
