(More customer reviews)SHURFLO WATER PUMP
ShurFlo Extreme Series Smart Sensor 5.7 gpm variable speed pump was purchased 8/5/2005. Pressure and flow was similar to household plumbing.In early July 2008, it lost pressure.After a faucet was turned off pump ran at very low speed for minutes to hours.If power was turned off and back on, the pump would stay off.No water leaks, no air in lines.Same problem with both freshwater tanks, suggesting not a problem with tubing between tanks and pump.
ShurFlo replaced the pump under warranty July 8, 2008.Pump replacement labor cost $150 and 4 hours in a waiting room.
If I had known the new pump would act like this, I would have fixed the old one.The old one had no adjustments, ran quietly and always at the perfect speed to meet volume demands.Replacement pump has pressure adjusting screw in the center of the pump head.
Replacement pump is unpredictable.Sometimes seems to work fairly well, then will surge and cycle or shut down.It is often noisy like a jack hammer.I have attempted to adjust it over the past 7 months without success.Several times I have thought it was adjusted correctly, only to have it change in the next day or so.It often acts like the entry level pump that led me to upgrade to Shurflo to begin with.It's no fun in the shower--high/low pressure & flow, hot/cold temperature.OW!
IT'S NOT JUST ME
RV Club Discussion Forum:
1. We just installed a new Shurflo 5.7 in our trailer to replace a Whisper King.We had a 5.7 in our last rig and were VERY pleased with it, until it failed. The new one I just installed is a warranty replacement from Shurflo and I just took the old one out, put the new one in.... and YIPES! The new one, at ANY speed, hammers like a jackhammer!!At first I thought I had an air leak in the intake, because that will sometimes cause a noise, but after getting a severely bruised armpit double-doing all the joints and making SURE there was no air leak, it still pounds like a hammer. And it does it all ALL speeds, fast or slow. Anybody had this type of thing happen to them? I emailed back to shurflo and got a couple of quick replys, neither of which were any help unfortunately. We've just come back home from a week in the woods, and the noisiest thing there was our pump.
2. The old water pump(shurflo 2.8) died last week so we took this as a chance to upgrade to a 5.7 Extreme . At first it worked fine but over the last 2 days it has gone downhill fast. whenever a faucet is opened it chatters or jackhammers terribly. the shower is almost unusable as the pump cycles off and on every 5-10 seconds causing the flow to almost stop and then take off again.
3. I went thru the same problems with my water pump. My OEM Shurflo 5.7 died, replaced it with a new one, this one had the spurts and hammering. I went thru 4 new pumps. I finally tried the competitor that worked but the pressure was not as good.
4. I have the referenced pump as part of my newly purchased RV. It's one funky pump. Starts & runs for about a second, stops for a second or so, then starts again and runs fine. Water Hammer/knocking/chatter: Does this sometimes. I've narrowed it down. If I'm connected to city water then disconnect and shift to the pump, I get the chatter. As previously discussed, I open two faucets, the pump chatters for perhaps 15 seconds then all's well.
I'm sure there are more aggravating machines but, at least to date, I've had the good fortune to not run into one. When this pump dies, it gets replaced by a non-Shurflow pump, warranty or not.
