It's a pump
Drop-in replacement for my failed UP 15-18 SU (after about 15 years of recycle service).

Easy install and great price
Easy to install when following Grundfos YouTube videos (albeit for a different model). Perfect replacement for older, discontinued model: UP 15-18 SU. Worked as expected, not quite silent, but not noisy either. Hope it lasts!

Works just as I had hoped
I agree with all of the other positive reviews. My pump arrived quickly with no issues. The only minor issue was the electrical connection box came with only 1 screw but needs 2 to secure it to the pump housing. No big deal and probably an issue for Grundfos to correct. I found the pump very easy to install and it appears to be working just fine for me.

This unit is awesome
I installed this with a recirc system last year with a timer and temperature thermister. This unit has been flawless and is quiet its so nice having hot water almost instantly at every faucet without wasting gallons. My water bill and electric bill have dropped substantially. I was nervous thinking I would hear the pump but it sits downstairs with the water heater and is close to silent.

Excellent product for my solar hot water system
Arrived on time, was easy to install and I am now back to free hot water! Much quieter than the old pump that this replaced.

Packaging Issues
This is the 3rd Grundfos pump in a row I've received in an unopened, undamaged package that had damaged spring terminals and / or other damage. I asked Pexunivers to check the pump before shipping to ensure it was in one piece before being shipped. Obviously they didn't. Maybe the great prices from Pexuniverse are because they buy damaged seconds from some junk warehouse and don't tell their customers. What ever the reason, beware of the merchandise you get. Examine it the day it is received as FedEx only gives you 2 days to report damage and still get free shipping back. Rating is a 3 because the pump works and Grundfos makes good pumps but their package results in damaged products after shipping.

Do Not buy this pump
The largest union sold to fit this pump is only 3/4 inch, while the ID of the pump inlet and outlet is 1 inch. Makes no sense, and no help from the company.

This is the best
"I installed a hot water circulator pump, with a NEW dedicated return line, back to the COLD water inlet of my water heater. A Grundfos pump was install in my last home and I was told this is the best pump made. After 10 years of non-stop trouble free use, in my old home, I only wanted a Grundfos in my new home. This Grundfos UP15-29SU Model allowed me to install the pump at the HOT outlet of the water heater with the 3/4"" Threaded Bronze Grundfos Pump Union Set #GU125 (that I bought at the same time) very quickly and with ease, using just a third part (one 3/4"" nipple) back into my old flex pipe that I just removed to install the pump on top of my water heater. This Stainless Steel Grundfos Pump is a beautiful piece of quality and PexUniverse.com as all the research available to pick the best style pump for your intended purpose along with the required Grundfos connection parts. Now my new home has HOT water at the bath/shower and sinks with-out the LONG wait and waste of running all that cold water down the drain."

Ask a Question
This Grundfos UP15-29SU Stainless Steel Circulator Pump, 1-1/4" Union, 1/6HP, 115V (59896775) can use for food application?
Helpful? Yes -1 No
The short answer to your question is no. Although Grundfos stainless steel circulator pumps are safe for handling domestic water, they are intended for use only in hot/cold water recirculating heating or cooling applications (such as radiant floor heating).
