Most Liked Positive Review

Just what the doctor ordered

If the longevity of its predecessor says anything (25 years) this puppy will endure. Same solid construction, complete instructions written in grammatically correct English.
VS

Most Liked Negative Review

I would not buy this product again.

This pump is used to circulate hot water through my baseboard heaters. It functions well, but is very noisy. I plan to replace it this summer so that we don't have to listen to the noise. The previous pump ran quietly for twenty-five years.

Replacing our existing recirc pump that has become noisy

Hot water recirc loop that keeps hot water ready in the kitchen and bathrooms. Replaced existing pump that started making noise after 10 years of constant service. Stops in the unions make the swap super easy and fast.

Great Pump for my HW recirc needs

Can't say enough good things about the UP15-29SU Circulator Pump 59896775 and the great purchasing support I received from the fine folks at SupplyHouse. They helped me find the exact replacement for my 19 year old recirc pump and got it to me in no time. Installation was a breeze and I had it running in about 15 minutes.

Yes

It is just what I was told it was. Easy to install and works great. Since I was able to install it myself I saved several hundred dollars by not having to hire a plumber.

Pump worked perfectly and quietly

Pump is quiet and is installed in a 3 bathroom house. Installed about a month ago and no complaints, so I guess it's doing it's job.

Q: Can this pump be used with a passive hot water recirculating system?

Asked by AudioHTIT 11 years ago

-

That would be the opposite of "passive" however if you wish to have both a pump and the option of a passive system you could simply bypass the pump using valves allowing you to re-route the flow. I don't know what the resistance of the pump is when it isn't running. Benjamin Straub Facility Manager, Canoe Island French Camp PO BOX 370 ORCAS WA 98280

Yes it would work depending on the flow of gallons per minute you require. It might also depend if you have a closed or open system and the height of the panels. I use it with a hot water heater and pex pipe in basement walls. I got the stainless steel because the cast iron pumps I had started rusting.

The simple answer is YES. I have a standard house setup, ie; water heater, with a supplemental solar system. Michael Carle

Q: does my UP15-29SU pump have a check valve built into it?

The pump does not have a built in check valve. You will need to place a check valve in line with the pump just up stream.

Q: I have the UP 15-18 SU pump part # 59896127and I am told the 5996775 is the replacement unit for this pump. But the connections look totally different. Will this unit hook up without all new plumbing connections?

Yes, it should. They both are Stainless Union Connections GU125. You just need to know what size and if it's solder or NPT.

Yes it should work if you don't have any leaks.

No. Will need some new connections, but try another pump.

Q: The pump I have know is Type UP 15-18SU, 115V 1PH 60Hz, P/N 59896127, PC 0151. Will the UP15-29SU be the same.

According to the manufacturer, these pumps are different. The UP15-18SU is obsolete and its replacement is the UP15-29SU. Dimensionally they will fit in the same piping arrangement.

I needed to find a replacement for that same pump. I used this pump and although it looks slightly different, I found the performance to be exactly the same.

Was this review helpful to you?
- Another PexSupply Customer

Yes these pumps are face-to-face replacements. However I have a problem. I ordered new valve/unions to replace the old ones which were badly corroded and non-functional for years. The new valve/unions were OK on the pump end but the flare fitting end did not match the old. The diameters appear the same but the threads/inch do not match. The new valves P/N is 59896775. A problem for me because the stupid plumber did not leave sufficient pipe protruding from the wall for me to cut and put the new flare nut and ferrule on. This may not apply to your situation-- good luck.   TV

yeah the UP15-29SU will work, should be 10 microfarad capacitor with flows to 12 gpm VOLTAGE: 115V make sure you mount it the right way.

- Another PexSupply Customer

After speaking with tech support at Grundfos, the 15-29 is an exact replacement to the 15-18 all the way down to the same flange size. If you'd like more information from Grundfos their # is***.****

The NBF-22U pump ( http://www.pexsupply.com/Bell-Gossett-103255-1-25-HP-NBF-22U-Bronze-Circulator-Pump-8641000-p ) is still available. Any other stainless steel, union connection pump that meets your system's GPM and head pressure requirements should be able to replace it.
