Used this pump to replace a B & G series 100. Make sure you check the flange orientation before buying. Motor should mount horizontally and the flange bolt pattern for this pump is horizontal. If the pump being replaced has flange with a vertical bolt pattern, you will need a 59896341 pump. Very nice pump.

My old pump was taking along time to heat the home when it was below freezing outside. I noticed that my pump was not installed per the vendors instructions. I discovered that this new pump comes in two orientations to solve my problem. Per instructions, the pump motor needs to be mounted in the horizontal position. Not pointing down or up. The new pump also has 3 flow settings to provide more flow where needed. After install, my house warms up much faster even on cold days.

The description says it has a time for pre-programmed usage times. It does not. It only has a 3 speed selector switch. Also, if you're replacing an existing pump you'll be fine, but if you're doing a new installation you'll need the plumbing flanges to adapt to pipe.

I have had multiple Grundfos pumps running flawlessly for well over a decade. I decided to purchase a replacement just in case I needed something. This pump is a perfect replacement part and an exact fit for the ones installed long, long ago. The speed adjustment is a nice feature. I will not even consider anything else.

I have two of these running in my house reliably for several years. That said, quality control must sux as a pump so f'd it won't prime should never go out the door. I literally poured water into the inlet and it would not prime/pump. Pulled the check valve out, re wired etc. real pain in the bauls. I'm thinking I should try a new brand. 3 hours of my life trying to prime this pos, plus wiring then unwiring, mounting, unmounting, boxing and returning. 5 hours of pissed off. Not worth using Grundfos again.
