3 Questions
Q: Can this pump work upside down? That is installed vertically but the flow goes from above to below? by Robert from Illinois on December 31, 2015
A: The pump can be installed in any orientation as long as the motor shaft is located horizontally. It is also best practice to have the terminal box on one side of the pump with the conduit entry facing down. Details can be found in the installation manual on page 7. by Bob, Product Expert
Q: Does this Grundfos 59896775 come with a built-in timer? by Dan from California on November 18, 2015
A: The Grundfos 59896775 (UP 15-29 SU) does not include a timer. The most similar pump that does is the 59896777 (UP 15-29 SUC/TLC), which also includes a check valve and line cord.
Alternatively, you can purchase a timer separately. For a new pump, you'll use the Grundfos 599388. by Bob, Product Expert
Q: My pump froze. Is there more to changing out the pump than shutting both gate valves and undoing the 4 bolts? by Mike from California on September 19, 2015
A: As long as there are isolation valves on either side of the pump, you should be okay. You might need new flanges if they are leaking. Please refer to the Grundfos UP Installation Manual for more details. by Bob, Product Expert
This unit replaces a 6 year old .....127 model. The old one (6 years) burned out due to my neglect. I'd turned off the water supply and forgot to unplug the timer while away for a week. This ...775 fit right into the old piping. Makes a little noise at first But I bled it from the top inserted screw. Nice and quiet. Pleased.
This replaced a like unit that was about seventeen years old. It circulates hot water throughout the 3000 sq ft house, so we have instant hot water at all the faucets. This pump is so quiet you have to touch it to see if it is running!
Pros:Durable, Quiet, Exceeded Expectations, I'd Buy It Again
My new pump was a direct replacement for a 14 year old pump. 20 minute install.
Thank you so much.

Perfect Match
Customer service was extremely helpful in assisting me in a replacement for an older model pump which was in the house when I purchased it. This model is a perfect fit.

Replaced Original Unit That Lasted 18 Years!
This pump circulates water throughout our hot water plumbing, and is mounted "upside down" on the hot water heater. Circulated water is returned to the heater via a "T" connection to the heaters drain valve. The original unit was installed when the house was built in 1998. When it's not working, it can take as long a 9 minutes to get hot water in the various sinks/showers.
The original likely only failed when I forgot to turn it off when to house water was shut of to do unrelated plumbing repairs. My only problem was finding the correct part number unit to replace my original unit, as models have changed since 1998. Note that the timer is an optional item. As we left our old unit on all the time, I did not bother to install a timer for the new unit. The old timer was still functional, but did not fit the new model pump.
Oh, I also had to buy a 15" Crescent wrench, as my trusty, 40 year old 12" wrench did not quite open far enough. When I went to Lowe's to purchase a 15" Crescent, there were four of them laying on the bottom of the wrench display. None of them had any labels or packaging, so apparently really cheap, tacky people had purchased them for one use, and then returned the wrench to the store! eComfort provided fast service, and was about half the price as the same pump on Amazon.
