Water pump is surging-What's next?
The water pump has worked fine up until a couple of weeks ago. I've noticed it is beginning to "surge" as the stream of water comes out "strong" and then "weak" and then "strong" etc. Prior to that i...

The original SHURflo water pump in our 2002 RoadTrek 200 Popular was so noisy and would cycle on and off at any but full flow. It caused the PEX pipes to rattle. One night in Yellowstone, a neighbor tenter asked me to not try to start the generator at night. I did not have a generator. That was us taking a shower. I put in a Flo-Jet variable speed pump and it was wonderful. The water flow was just like we were connected to city water. The 2009 Itasca Navion had essentially the same pump and very similar problem. I elected to put in a SHURflo variable speed pump. Much improvement, but not as quiet and smooth flow as was our experience with the Flo-Jet, but swaping out the pump was easy. I will say this; If I were to do that again, I would install a relay at the pump and a heavy gauge wire back to the panel. The voltage drop caused by the reletively small gauge and the remote on/off pump switches would make the pump not work properly at times when only on battery power. The replacement pump failed after about a year (bearings) and SHURflo sent me a new one without hesitation. Worked OK from then on. I anticipated having to upgrade the pump when we ordered the 2018 Winnebago Navion 24G, but while it is not perfectly quiet and does cycle to some degree, I don't think it merits replacement. I believe the pump is a new design (4008 Revolution) with a by-pass feature that reduces rapid cycling and an accumulator tank is not recommended. On the 24G floor plan, the Truma tankless water heater and Thetford Tecma toilet are standard. A good pump is essential so that those features function problerly. Since the original pump is working out fine, I have not looked into the current offerings for replacements. From experience I have learned, the only way you are going to be happy with the results of an upgrade, don't go cheap. Get the best pump you can.
A quick search just now: I would go with Flojet V-Flo Constant Flow Water Pressure Pump if I had to replace mine. Pretty expensive, but if this pump is anything like the Flo-Jet we had before, it would be worth it. A couple of years ago when I was helping a friend with his pump problems on his fifth-wheel, I looked into some options. After reading the reviews on brands other than SHURflo or Flo-Jet, I think sticking to those would be a good bet.
