Question:
I have a 2006 Tiffin Phaeton 40QDH and I need to replace my fresh water pump. Its making a lot of noise and sounds like its ready to give out. The current pump is 2088-422-144 I dont know the manufacture. It runs at 2.8 GPM, 12 VDC. 7.0 Amps, with 45PSI. Im looking for a replacement. Do you have a replacement available. Thanks. JG

Hey John, what you have now is a Shurflo, but more important to that is the specs you listed. So for a suitable replacement the Seaflo part # SE58FR would be your best option. It is the same PSI rating of 45 psi but can flow a little more at 3 gallons per minute. The max amp draw is 8 amps too. How long did your water pump last? Was it the original?

Thanks for the information. The pump is still working but it's making a lot of noise when the water is turned on. I did notice that the pump continued to run after the water was turned off. Had to turn the Water Pump switch off to stop it. That was a first. Went out to check on it and it definitely got hot; not leaking. I believe it's the original pump that came with the Moterhome Is the Seaflo # SE58FR difficult to install? My current pump is located in my water bay so there should be enough room. Will I have any issues installing this pump into a 2006 Tiffin Phaeton 40DQH Class A Motorhome? Are there any additional parts that I need to purchase to replace the existing water pump with the Seaflo SE58FR?
