Great pump, excellent price, fast delivery. My old pump was making a screeching noise, replaced with this pump and it's now quiet again.
Right part, right price
bolted right up. It's extremely quiet. I'm very satisfied, was delivered on time. I would recommend to everyone.
delivered as advertised in satisfactory condition.
Liked the unit and it was easy to instal
Hesting unit in our house. It was very easy to install. The screws on the electric cap did not fit.
Used the Grundfos to replace a Taco 007 as the circulator in a baseboard hot water system. It's alot quieter than the Taco was both at the pump and throughout the house. Previously I could hear the pump humming through the pipes even on the second floor of the house. No humming noise with this Grunfos. I would buy this pump again for sure.
Best Prices by Far !!!!
Product was shipped and delivered fast, and in perfect condition. Saved lots of $$$ ordering from you !!!! Thank You, Mark
We not have heat on the first floor!
Easy to install. Works fine. My second. This was on the first zone of a hot water system that heated our first floor. Second floor was by our first Grundfos pump.
This is an excellent product
There are similar pumps available, but the Grundfos UP15-42F is well suited for residential heating systems; economical and reliable.
Replaced an older leaking circulator with this one. Installation was easy. Recommend by flanges at same time.
home use or not
I went to switch out the pump at my home and am installing the same as coming out Grundfos 15-42f but read further and said this pump is cast iron. It seems like they dont recommend this for home use. Sounds like they recommend stainless "cast iron circulator designed for use in closed loop heating applications, such as radiant heating, baseboards, fan coils, etc.Grundfos..." Any comments if cast iron is safe to use, it is for hot water recirculating in my home.
Pump works just as i thought it would.
Use the pump as a cirulating pump for hot water in my home
I need to replace my pump and I currently have this model. What would be the advantages of using a 3-speed instead?

If this model works for you, there's no need to replace it with a different one. A 3-speed circulator has a manual Low/Medium/High switch which gives user the functionality of 3 pumps in one.

Pump seems to work well, but not consistently. Water comes out hot when the cold water is turned on. Plus when it does come out hot on either the hot or cold faucets, neither lasts long. Also, the pump does not distribute hot water throughout the whole house. I am having to unplug the pump in order to take a shower in the upstairs bath.

If you're using this circulator pump for pressure boosting applications, it will not work because it is not designed for such applications. Similarly, cast iron circulators are not intended for use in domestic hot water recirculating applications, as they corrode rather quickly when exposed to fresh (oxygenated) water. Instead, a stainless steel or bronze circulator pump is used. Your specific issue may not necessarily be associated with the above, but could originate from the way the system is piped or other system components, since circulator's operation is rather simple - it is either on or off.
