## Description

COMFORT PM AUTO 115V 1-1/4 PUM

Review: Replacement - Needed to replace a 9 year old Grundfos due to the auto adapt function not working. Prices varied quite a bit between desertcart, Home Depot and various supply houses. That got me wondering if all were the same pump, so I started a text with Grundfos customer service. They were closed over the holidays, so it took me two weeks to finally connect with a rep. She was very helpful in telling me the 98420224 UP 10-16 A PM BU/LC pumps were all the same regardless who sold them. The replacement arrived within a week. I was very fortunate in that the plumber who plumbed my new home installed 1/2" shut off valves on each side of the pump, so isolating the valve was easy. I read the directions that came with the pump several times. The directions appear to have been updated in early 2024, so they were much improved over other reviews. With a large crescent and channel lock wrenches, the old pump came out easily. The new pump was exactly the same size so it went as easily. I was cautioned by the customer service rep to be very careful with the auto adapt cable and followed the directions verbatim. After flushing in both directions to ensure the pump had water, it plugs in and works well. An easy task.
Review: Direct replacement for an older model and works great. Easy installation. - Product arrived as described. Installation was easy. This version is a newer version of the model I had, but on the Grundfos website, it stated it was a direct replacement which is accurate.

## Questions & Answers

**Q: Does it turn itself off when the water from the return line is hot?**
A: In Auto mode, the unit will run only when it 'believes' you will need hot water based on your usage over the last two weeks, so most of the time the pump is not running. In 100% mode, the pump runs at all times. In temperature mode the pump will turn off when the water in the re circulation line is still hot, then turn on to circulate hot water as the return line cools.

**Q: Is this a replacement for the discontinued #96433902?**
A: The unit that I replaced was #97525922   UP10-16 BU/ATLC.. The contection flanges matched, which made the swap easy. I didn't have to change any plumbing.

**Q: What is the dimension between the two pipe connections?  the cut sheet for up 10-16 a pm bu/lc shows 4.33 inches.  the photo here looks much longer.**
A: I'm unsure as to what picture you're looking at.  Recently had a new water heater installed.  The configuration of pipes are 2 in 10" increments to the downspout of the water heater with one about 4" to the pump.  Hope that helps.  Whoever installs it would know what you need.

**Q: Can you use this pump without a dedicated return line if the Grundfos under-sink valves are purchased separately?**
A: PUMP DESIGNED TO DISCHARGE INTO DRAIN VALVE OF Water heater.  RETURN LINE MUST BE RUN FROM FURTHERIST HOT WATER LINE IN THE HOME TO PUMP INTAKE. THIS PROVIDES HOT WATER LOOP FOR ALL FIXTURES

### ⭐⭐⭐⭐⭐ Small, quiet, easy to install.
*by J***R on October 4, 2025*

Love the adaptive recirculation. It recognizes our water use patterns and has the water hot at the faucet when we need it most. Saves about 5 gallons of water daily not having to wait for the water to get hot to our shower. Very small and takes up little space. Very quiet and uses less electricity than most pumps.
