Coach Water Pump

Anyone had problems with their ShurFLo coach water pump? The one in my Berky is a model 5900, supposedly top-of-the line pump. It has an electronic computer module on it.

Anyhow, mine has quit running. I've tested 13+ volts at the pump so it's getting power. I've also tested the pressure switch so that's not the problem.

Interestingly, ShurFlo offers two different warranties, depending upon whether it was OEM (installed by FR) or bought directly by the end user. If OEM 1 Year, if direct sale 3 years. I'm 3 months away from 3 years but of course that does me no good since it's OEM'ed. Does that suck or what??

Boowho??

Water Pump

boohoo,

Last year while in the Palm Springs area my model 5900 that came with the coach failed. I called the 800 number and got hold of a guy who happened to be at the factory near LA. After a short conversation I removed the old pump drove a 100 miles gave it to him, he gave me the replacement (which is not the 5900 but the newest one), fittings, filter a hand shake and I was on my way. No questions asked, he said the pump should not have failed and apologized. At the time the factory was moving to a nearby location. Super guy, super satisfaction and I was amazed that it could happen today. No warrenty paperwork at all, none, no bull, no runaround and no problems with the replacement.
My coach is a 2008 360QS but I bought it new in June 2011.

These are my log notes on the problem:

Monday 13 February 2012

Called ShurFlo 800-854-3218 ex. 6785
Spoke with Pedro, he said bring old pump to him at:
5900 Katella Ave
Cypress, CA 90603
And he will swap for replacement pump, no charges; just bring some paperwork as to this being a new coach.
Hours are Mon-Fri 7:00-3:30 local time

Smart Sensor 5900-0201 is no longer available
Replacement is Revolution 4008-101-A65 or e65


Removed pump and went to see Pedro in Cypress on Tuesday 14 February 2012. Swapped pump for the 4008 model and installed it in the coach, all seems to work well.

Well, IMHO you got lucky as they go by the manufacture date stamped on the pump which I'll bet is long past (even though your coach is new; maybe FR would have helped out).

The replacement Revolution pump you mention is a lot "lighter" as far as I can see. BUT, a LOT cheaper too!!!

I figured I had nothing to lose so I seriously dug into the pump. There is in fact an electronic "module" in there that the power goes through. I also checked the motor for a frozen bearing; shaft turned as smooth as I've ever seen anything turn.

SO, being sly, I decided to connect the 13V supply wires directly to the pump motor leaving everything else out of the loop. Had good 13.2 volts, but the motor would not spin up. And yes, the 13 was really there; checked with a multi-meter.

Now I'm thinking that maybe a winding in the motor may have an open, or other similar problem. Too late for today, as DW is making din-din. But tomorrow AM I'm going to disassemble the motor itself and see if I can find anything.

Am I having fun yet?? NO!!! I'm pretty good at mechanical and electric things, but HATE to work on that stuff.

Boowho??

How much is a new pump? It seems like a good part to have on hand if its not cost prohibitive.

Phil, I have found the replacement pump for as little as $60 on Ebay plus shipping of around $14.

Camping World is around $95 I think.

Either way it will not be the original pump as that one is no longer made. There are a few (at least) in the "pipeline"; Amazon has one for around $250. The replacement pump has nowhere near the capacity as the original regards to max pressure and GPM flow.

I figured out this morning that my problem is likely the brushes in the motor. I opened the motor and one of the brushes was not touching the commutator. It was stuck so I loosened it, but am heading to the auto parts store to get some graphite to lubricate the brushes.

If that works and there is nothing else wrong, I'm a happy camper.


Boowho??

UPDATE:

Put the lubricant (the stuff they use for brake pads) on the brush holders to make the brushes move more freely. Got some on the contact side of the brush, so when I put motor back together and tried to run, no go.

Took it apart once again, cleaned the excess off the brushes, re-assemble and Voila!! we're pumping water again. Am going to search for some spare "generic" brushes and the matching springs to use for "insurance" in case this happens again.

DW thinks a complete spare pump would not be a bad idea, but besides being sly I'm also cheap.

Good job boo. I would think with new brushes it will last a long time. If you have a spare it will never need to be replaced. Or it will last until you forget where you put the new one. Post what brushes you find. I think I will put some in my tool box.

I thought I was the only one who forgets where I put things.

I have two and sometimes 3 of the same thing because I forget where I put the original plus the spare. The good thing about having three of something; it significantly increases the odds of finding one of the three when you need it!
