poor quality and not 1 " NPT.

This pump is just a copy of Grundfos 59896155 and not 1" NPT. Never use this pump for underfloor heating and radiant manifolds as its flange size is different from the description.

Pros
  • Tools and housewares
Cons
  • I will add later

Quality is lower than low

I have purchased three of these pumps and three times at different times. The first of the pumps worked for a day before I removed it for another solution. The other two were purchased for delayed work. The only pump that worked was that it only worked in one physical orientation which the manual says CANNOT be used. The other two didn't work at all. All three pumps showed that the main shaft came loose when shaken. All three pump flanges had 1 inch iron pipe threads that were too large to seal

It's amazing how some products can look the same, but they are.

I bought this pump 5 months ago and only 2 months ago I hooked it up for underfloor heating. I woke up one morning to a loud whistle. I suspect that the pump bearings are already defective. When I tried the customer service number provided, the call could not be completed. It's amazing how some products can look the same but vary so much in quality. Maybe look for a higher quality pump? Since I first posted this I have noticed that the direction of the motor is now turning in the wrong…

Pros
  • Rough plumbing
Cons
  • Good but not great
