I would like to buy a spare water pump for my 2001 26.5 RB, so that in case it ever goes out while Boondocking, I have a spare. What do you recommend to buy for the spare? A Sureflo Revolution?
Thanks,
Steve
Good idea, I have replace our 2004 MB water pump twice because we did a lot of boondocking when touring American west. The water pumps did make their contribution to our daily life. Some of Shuflow pumps had a failure mode upon heavy use, the bolts that seals the pump body to motor became loose because of insufficient thread engagement, causing a slow leak. This happened to the pumps made in Mexico. I had to pull those bolts out, slightly enlarge the holes, and replace them with longer bolts, retighten with a nut and a locking washer for each of them. It would be disasters if we did not have a spare in hand. Later I sent photos to Shuflow, they told me they knew this failure mode but has been corrected. The did ship me a curtsey replacement free of charge.
You can find the water pump model in the spec sheet, just replace them with the same model.

Your 2001 LD, if original, most likely has a Whisper King pump, a rare pump to find today. I would open the cabinet and see what pump it presently has.
The Revolution 4008 is a popular pump and a good choice for replacement, it may require longer 1/2" flexible water tubing if replacing a Whisper King..

I have a second Whisper King in my 2003 TK, but have a 4008 in the compartment as a spare. The Whisper King has not been manufactured for a few years.

Hi Joan; I still have my original Whisper King, But I think I should get a spare pump, at least at home. Which one do you have 'waiting in the wings'. Amazon has the A65. I assume the 3.0 GPM is appropriate for our TK. Any thoughts on the two hose silencing kit, water strainer, or benefit of the accumulator tank. I haven't looked recently, but I suspect there wouldn't be room for the accumulator. RonB

ShruFlow’s Revolution 4008, 3-gallon a minute pump is a suggested replacement.
A silencing kit is a good idea but forget about the accumulator, ShurFlow’s instructions tell not to use one, I tried and it upset the pump’s controls.

Awhile back, I heard the Whisper King was going away.
This was years after the replacement came out, which seemed to have problems.
So I went and found a Whisper King on the shelf at an RV place and put it in my compartment.
My original is still working OK after 25 years but when it does finally fail, I like having a new one ready to go.
Amazon has the ShruFlow 4008-101-A65 $59.00
4008 -101-E65 $60.99 - $72.95
Do you have a preference? Both look like they are 3.0 GPM.
Thanks

According to the Shurflo pump replacement chart (above post), the A-65 is the OEM pump. The E-65 is the "aftermarket" pump. I have no idea what the difference is, if any, between the two pumps, but a call to Shurflo could probably provide the answer.
We got the silencing kit we but didn't notice any difference (it was just flexible hoses). Instead I would suggest doing something so the pump is not flat against wood (e.g. rubber underneath or rubber washers or something that will still have it be secure but dampen the vibrations).
In the newer models, the water pump is pretty quiet. The mothership built this little frame for the pump. It’s hard to see in the photo but It is mounted on rubber and there is good sound dampening. The photo was taken when I had the convertor pulled out to accommodate winterizing so ignore the misc. hose and fittings.
A spare pump is on my list of future purchases.

The 'frame' is mounted on the floor, a much thicker, denser surface than the typical vertical cabinet surface. With no adjacent thin panels to vibrate, this may be why it is pretty quiet. The pump in our '83 was floor mounted, and also fairly quiet.

Intteresting mount for the water pump, I have not noticed one before. Wish the photo showed more of it.
Your LD has the first galvanized plumbing fitting I have seen in a LD, previouly all have been plastic or brass.

It would be interesting to find out if other 2017 and later LDs have both the pump "cradle" and the galvanized fitting; might these modifications have been done by the previous owner of this 2017?
I believe that is part of his winterizing hardware. He and I had a discussion about plastic fittings and steel threads.
Jon
Yes, the galvanized fittings are part of my blow out hose for winterizing. Sorry for the confusion!

I think not since I’m the one that showed him where the water pump was, LOL!
Ah, OK; got it. ;) So glad I don't have to winterize!

It’s better not to use galvanize steel fittings in an RV, they rust and can cause flakes in the system. RVs tend to be parked for extended periods of time in which steel plumbing can oxidize, plastic and brass do not suffer from such problems.
Plastic and brass are preferred.
Larry
For clarification, the galvanized fittings are only used when winterizing. It’s part of the blow out airhose assembly. They are not installed.
Here’s a couple of photos of what the water pump mount looks like with the converter installed and without the winterizing blowout hose in the way.
Here are the photos for the Shuflow pump failure mode (slow leaking) I was talking about. Had to use longer bolt and reverse direction for the emergency repair.
I just had the head leak on my 99s whisper king. While I don't have the paperwork, I think it might be a replacement WK, and is a 2093 204 114, which is only a 2gpm. Were most of these originally 3gpm, or the more important question, should they be?
The Whisper King has not been made for a few years, but, as far as I know, it was/is a 2 gpm pump. I have a Whisper King in my 2003; it's the second one. When it dies, there's a 4008 in the compartment waiting to be installed.

Thanks. For some reason I have this vague recollection that the PO told me some story about how he had it replaced with this lower 40psi pump so that it was "safer" for the plumbing. Hopefully I don't move to a 55psi, and discover that this was some bandaid holding in some other leak...
The 114 I have isn't listed on that conversion chart. I think they only have 2 12v 4008s, a 3gpm at 55psi or a 2.3gpm at 50psi, so my choices have been well narrowed for me it sounds like.
Hi McNugget; Odd timing, but my original '99 Shurflo developed a leak during the Morro Bay trip. I got the 4008 replacement. Took a week to get here in San Diego, from Oceanside, by way of Indiana. It's not installed yet. Sealed the wood floor, a drip tray is in, and I'm modifying some wiring to put a switch/light in the bathroom. Easy to do in the TK. Not going the three way switch method, just another switch in parallel. The old pump just developed a leak in a seal at the bottom. My old pump was a three chamber, and marked for 2.75 gpm. The new pump is a four chamber pump, marked for 3.0 gpm. Amazon.com: SHURflo 12v 3.0 GPM Revolution RV Water Pump # 4008-101-A65:...

An 'issue' with repairing or replacing the water pump in an older TK is that access to the pump is only through the small opening when the bottom drawer in the sink set-up is removed. Newer TKs may have easier/more convenient access, but trying to even see into the tiny space, let alone get ones hands in there to work on or replace a pump in an older TK is not easy. I ended up having a shop replace the original water pump; young, limber tech with non-ham hands. ;)
Hi Joan; Yes slow, tight access. When I first got 'Bluebelle', I didn't like the way the drawers didn't pull out all the way, so I changed all three to accuride full extension drawer slides. I had to cut away face frame on each side of the drawers to put the side rails in. The 'closed' retainers didn't work, so I put magnet catches to hold them shut at the backs. They work Really well! Even today 19 years later I find myself trying to lift them, even though I just have to pull hard. I've been able to access behind and under easily. If something pops up to prevent a drawer from opening, I can pull out all three clear at once, and I can retrieve things that fall out the backs onto the pump.
Working on the pump, I pulled out all 3 drawers just by flipping a little lever on each slide. The side rails are still in the way, but not like the original center slides would have been. I took out the LPG detector temporarily to expose more from the side. 3832E|Classic Full-Extension Slide|Accuride International (https://www.accuride.com/en-us/products/3832e-light-duty-full-extension-slide-with-lever-disconnect)
Newer models of LD TK's reversed the drawers and cabinets, so that the drawers pull out from the driver side. So I assume the pump stayed in the same location, and with the floor inside the cabinet removed; it should be easier to access the pump. I'll try to come up with some pictures. RonB
On my 1985 twin/king, I cut a hole in the side of the cabinet where the water pump was located and added an access door. See this "Improving Gertie" page (http://www.andybaird.com/travels/gertie/improv_kitchen.htm) and scroll to the bottom.
Resurrecting this older thread mostly because the pics from #10 and #20 had me thinking about adding the upright housing to my 2001 MB. My pump died and I’ve already got the replacement working, but that upright housing looks pretty sweet for future replacement work. Any reason why I should not attempt this (as long as there’s no strain on the in/out pipes)?
Thanks in advance.

Hi Chris; (not Horst). I would mount the pump with the motor up. That way leaks won't get into the motor, and the inlet to the pump will be more on the level of the bottom of the tank. With low amounts of water, should you lose prime, it might take awhile to get water back into the pump with the inlet 10" higher. I would put a drip tray underneath, and a powered electric water detector in the tray. In my case with a 'TK, 12v is available right at the LP gas detector with it right there.

I'd locate the detector where it would be easy to change the 9v. battery. RonB
Although this post is a couple of years old, I now have a little more experience concerning carrying a spare water pump that could potentially help another newbie like myself!
I had read about the problems with the model in my '09 (shurflo extreme 5.7) so I carried a Revolution 4008-101-A65 just in case. Sure enough on our first big trip last year the Extreme did act up, though not enough for me to replace it at the time. Good thing I didn't try to replace it on the road since the Extreme's intake connection isn't compatible with the Revolution's. When I went to swap them out this summer I realized this. It was also a major P.I.T.A to get the correct connection.
Make sure you have all the needed parts along with the Evolution 4008 replacement if replacing another model pump!
I needed the Shurflo Swivel Elbow part# 244-3926 for the intake side of the Revolution 4008 pump.
