This pump is used in a two zone wood and gas fired boiler system for infloor heating and radiators on the second floor. The pumps I ordered were less than half the cost of purchasing this pump in Canada, including shipping. They are a must have in my system so I need to keep two spares on hand. I live 2 hours away from a major centre and it's nice to know I can afford to have two of these pumps on hand. Easy installation for anyone with even a little bit of handyman genes.

It was defective

I have several Grundfos pumps. Some are still working after 18 years. This one did not work out of the box. I did purchase a Grundfos pump locally and it is functioning fine.

I built my house in 1978 and have used these pumps to recirculate water through a fireplace jacket that heats a 2000 sq. ft. home with no problem. The first pump lasted over 17 years, I'm on the second one now and I bought this new one recently, thinking that it might be time for some problems, but so far the second one is still working fine. Who knows, I may never need the new one!

  • UP15-42F, Circulator Pump, 1/25 HP, 115 volt

    Q:

    I just received the grundfos pump. My old pump was the late bell and grossett motor/pump combo. My home is approx. 2500 square foot and it is a ranch type home. What I want to know is will the UP-15 42 be sufficient for this application?
    Asked on 4/16/2014 by Harv from Oshkosh,wi

    • CUSTOMER CARE

      A:

      It depends on the flow and head pressure requirements of the system. These are based heavily on the insulation quality of the house, the piping layout, and the size of system piping. You may want to find the model number of the Bell & Gossett pump in order to compare its pump curve to that of this Grundfos pump. You can also try to calculate the actual flow and head pressure requirements by using the document at the link below.

    Q:

    Can this pump be slowed down for the GPM flow? It runs as 17GPM and I'm needing about half that flow rate. Thank you.
    Asked on 2/5/2014 by DrewPalmer04 from Christopher, IL

    2 answers

    • CUSTOMER CARE

      A:

      Most circulator pumps operate along a single pump curve. The amount of flow a pump can circulate depends on the head pressure it needs to overcome. Head pressure and flow rate have an inverse relationship. The maximum flow rating assumes that there is virtually no head pressure. Depending on the head pressure in your system, this pump may be able to provide about 8.5 GPM.

      Not unless it is a multi speed pump. You could put in a ball valve and slow
      down the flow.

      A:

      The instructions that come with that pump have very helpful pictures on how to properly install it.
      However, I can put into words.
      1) that pump can be installed vertically or horizontally.
      2) Always install this pump so you can face the motor after it it installed..
      3) As you face the motor remove the four alan head screws.
      MAKE SURE YOU HAVE DRAINED THE WATER OUT BEFORE YOU DO THIS!!!
      4) Rotate the pump so you can read the information on the end of the pump.
      it should say Grundfos and the pump model. The black electrical box should be on the left.
      5) tighten up the four alan head screws.

      A:

      I shut my pump off one spring and the next winter I turned it on and it was making noises/failed. I'm not sure of the age of the pump, nor can I say if I just left the pump run all spring/summer/fall if it would have failed anyway. After replacing my pump I now leave the pump run year round and just shut off the gas to the boiler. I open all my zones so water flows. The basement floor (55 degrees) may warm up a tad in the summer months and maybe (marginally) cool the upstairs zones.  Geo-thermal cooling to some degree..

      Circulation pumps are best left running continually. If the pump is left idle for long it will begin to rust and may jam, preventing restart

      The hot pump says the motor is probably running. There are 2 other things that may be wrong. 1. the impeller may be worn out or has come loose from the shaft. 2. there may be an air lock in the circulating fluid.

      Maybe but not if the pump is circulating cold water. If the source fluid is

      As a general rule yes. If you have given them the model number of what is
      there now and they have recommended a replacement pump, that pump will come
      with replacement gaskets and should fit the existing flanges.

    • VERIFIED BUYER

      A:

      No, it's not repairable, or rather not worth repairing since the replacement
      cost is fairly cheap. I had one go bad after 8 years so the life span is
      worth buying a new one. The bearings had burned out on it so that it would
      hum quietly but not pump. As far as the direction of flow, just follow the
      arrow on the casting. Both of the flanges are the same so all you have to do
      is flip the motor over and it will still work. There should be a valve on
      either side of the pump that is turned with a large flathead screwdriver,
      this makes it very easy to replace. Hope this helps.

      Part 59896167 is the rotated flange version of this circulator. The cartridge (part G-506171 on our site) can be replaced, but there could also be air in the system that is causing the unit not to work properly.

      A:

      We wouldn't recommend it because this circulator pump is cast iron. The oxygen in present in potable water causes cast iron to rust, which can discolor and contaminate drinking water. When dealing with a plumbing system or an open heating system you should always use a bronze or stainless steel circulator.
