Product Q&A
12 QuestionsQ: I currently have a Grundfos UP10-16BU/ATLC hot water recirculation pump that was installed as part of new construction near the water heater. It has only been in service for 3 years and has already failed. It is making a rattling noise & stops pumping. I have read that there are no repair parts for this pump and am looking for a suitable replacement pump that will hopefully have a longer service life. We have softened well water. I can install an external timer if the replacement pump does not have one built-in.

Verified Reply- SupplyHouse StaffThis pump is a commonly used and installed unit so there isn't another pump that would really be listed as an alternative at this time.

Q: I have this pump and because of the 14.7 gpm its eating the copper pipe between it and the water heater.Any fix ?
Asked by Bill 13 years ago
Add your answer
According to the pump curve 9.5gpm is the highest flow it will achieve and that is with zero head. Even at that flow rate the velocities are within acceptable range for a ½" pipe. Even at the unlikely flow of 14.7 the velocity would not be high enough for pipe erosion, I would look at other sources like galvanic or chemical corrosion.
Q: I have this pump without a flange set. Can I just sweat a copper coupling onto it, then transition to pex, or do I need to get the flange set seperately?
Asked by Robb 14 years ago

Verified Reply- PexSupply StaffThis pump does not use flanges. Instead, it has 1/2" sweat connections.
You can sweat copper right onto the pump. The picture depicts that you have a flange type, but the details describe that it is actually sweat, so you are good to go. Brian Janes Drains Plus Inc.
It is possible by using silver solder. The risk of thermal damage to the unit will be high, any future leaks at this joint will be unrepairable after the unit is full of water. The flanges are low cost and allow for quick change out and never leak. If you are not experienced with silver solder and how to protect the unit from the heat developed you will damage the pump.Buy the flanges you will be way ahead.
As with so many similar situations, there may be several ways to do any one thing, however, I prefer using the addition of a separate flange set. The set is threaded to accept a "npt" nipple and then you can transition to a pex fitting. To me this makes for a much better overall solution. The flange set also serves to provide a substantial support for the weight of the pump however you may be attaching your pump to a support. G Lewis
I have the same pump it will not receive a coupling but you can sweat a 1/2" into the pump. Sent from my iPad
Q: how much energy does this pump use
Asked by nick 14 years ago
Add your answer
120 volt pump above uses 25 watts...
Multiply indicated operating current (amperage) times voltage to obtain power consumption in watts. Energy expense will depend on local kilowatt per hour utility charge and daily motor run time.
Each hp uses 745.7 watts, so dived by 25, this pump, in theory, should require 30 watts while running. There will be the usual spike at startup, though.
1 hp = 746 watts. thus 1/25 hp = about 30 watts
I really don't know, I have it on a timer and run it about 14 hours a day. It does it's job though.
$0.0013 /Hr @ $0.0472 /KWH utility rate
Q: Is this the appropriate replacement for an old UP15-18 SU? If so, is there a kit needed to install after the old pump is removed?

Verified Reply- PexSupply Staff59896775 would be a better choice because it also has union connections. No kit is needed for installation.
Q: I've been trying to decide which circulating pump I need to use to pump hot water from an indirect-fired tank I'll be getting soon, and I'm wondering if this pump will be powerful enough for my needs? 2.5 story house, 3 bathrooms/2 showers, 2 kitchens.

Verified Reply- PexSupply StaffIf you are looking for a hot water recirculation pump, then this would work for you.
We've had one in our home, 4 bedroom, 3.5 baths, 2 story, for 15 years. No problems. Works great. We have a very long run from water heater to 2 of the bathrooms. If it is off it takes about 30 seconds to get hot water to the far bathrooms when you turn it on.
Q: I just had one of these installed to replace the one that failed due to a leak. The pump runs continiously and hums. There is also a vibration in my water heater as the pump runs. The unit gets very hot. Is this normal?
