Spare water pump. September 19, 2020, 07:56:12 pm 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
Re: Spare water pump. Reply #1 – January 05, 2021, 06:39:24 pm 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. 1 Likes

What do you recommend to buy for the spare? A Sureflo Revolution?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.. Larry
Re: Spare water pump. Reply #3 – January 07, 2021, 11:22:55 am 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.This water pump replacement chart from Shurflo may be helpful:https://www.pentair.com/content/dam/extranet/product-related/product-photo/hypro_shurflo/shurflo/RV-Pump-Conversion-Chart.pdf 1 Likes
Re: Spare water pump. Reply #4 – January 07, 2021, 12:38:02 pm 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

Any thoughts on the two hose silencing kit, water strainer, or benefit of the accumulator tank. 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.Larry
Re: Spare water pump. Reply #6 – January 07, 2021, 01:02:15 pm 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.
Re: Spare water pump. Reply #7 – January 07, 2021, 01:26:58 pm Amazon has the ShruFlow 4008-101-A65 $59.00 4008 -101-E65 $60.99 - $72.95Do you have a preference? Both look like they are 3.0 GPM.ThanksTony R. (aka codefour)
Re: Spare water pump. Reply #8 – January 07, 2021, 02:24:32 pm 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. 1 Likes
Re: Spare water pump. Reply #9 – January 13, 2021, 02:57:01 am 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).
Re: Spare water pump. Reply #10 – January 13, 2021, 08:25:37 am 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 mothership built this little frame for the pump.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.Steve 1 Likes

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.Larry

Reply #13 – January 13, 2021, 01:22:40 pm "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?
Re: Spare water pump. Reply #14 – January 13, 2021, 01:43:27 pm I believe that is part of his winterizing hardware. He and I had a discussion about plastic fittings and steel threads.Jon
Re: Spare water pump. Reply #15 – January 13, 2021, 01:59:25 pm Yes, the galvanized fittings are part of my blow out hose for winterizing. Sorry for the confusion!

Re: Spare water pump. Reply #17 – January 13, 2021, 02:03:42 pm Ah, OK; got it. So glad I don't have to winterize! 1 Likes

Sorry for the confusion!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 2 Likes
Re: Spare water pump. Reply #19 – January 13, 2021, 02:52:08 pm For clarification, the galvanized fittings are only used when winterizing. It’s part of the blow out airhose assembly. They are not installed.
Re: Spare water pump. Reply #20 – January 13, 2021, 04:47:28 pm 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.
Re: Spare water pump. Reply #21 – January 13, 2021, 06:20:04 pm 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.
Re: Spare water pump. Reply #22 – April 07, 2021, 07:03:24 pm 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?
Re: Spare water pump. Reply #23 – April 07, 2021, 07:13:22 pm 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.This 'Shurflo' conversion chart may be useful.https://www.pentair.com/content/dam/extranet/product-related/product-photo/hypro_shurflo/shurflo/RV-Pump-Conversion-Chart.pdf 1 Likes
Re: Spare water pump. Reply #24 – April 07, 2021, 07:39:32 pm 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.
