Shurflo pump

by rgermain Sat Jul 08, 2023 12:45 pm

So glad that I bought a spare Shurflo pump when Halfords had them at £55.last night in France my shurflo gave up on us. I had been making a strange noise for a couple of days and did not stop straight away when tap closed. Spare pump fitted in 1/2hr with no swearing, wife took dog for a walk and was amazed I had done it when she returned. Will order another pump when home, but will shop around as the price has shot up. Thought at the time it was an overkill, but not so now.

Very unusual for a Shurflo to give problems at all.

by AutoSleepy_Don Sat Jul 08, 2023 1:45 pm

To me, this is the big advantage of the Shurflo i.e. that it can be swapped out so easily.
AS should not be fitting a submersible pump to an underslung tank.

Yes I thought that also.
Just wondering if it got too hot as the weather here has been very hot and also I mounted it along side the water heater as I thought it was the best place for it. Space on our Duo is tight, as we have a cut out along the off side bench seat. Might have to find a better place for it when home, although it will need longer pipe run. New pump switches off immediately I turn taps off. I did not refit the expansion tank as I found it made no change to way pump worked.

Do you think it was a heat problem? I will give it a test when I return to UK.

Yes was easy to swop out, I think Grommit put me on to the idea some years ago.

Well they say it comes in 3s

Had a bad fall in Millau, new gas tank regulator packed up, then pump. Home Tuesday fingers crossed.

I’ve just had to change gas regulator at 4 years old. Had very slight weep between regulator and crash sensor. I thought these things went on for years. Guess not always the case.

You're lucky! The pump on my new to me Duetto doesn't work, it took me a while to even find it! It's under the cooker, behind the false back that has the 240v circuit breakers and the water heater controls. Despite removing all the screws and plastic blanks, I had to cut the wooden panel in half to expose the pump. I've yet to fit the new pump (£60, eBay) due to me having a bit of surgery which precludes lying on my side swearing profusely!!!

Can anyone help/advise?
I have an Auto-sleeper Broadway EK TB and the submersible pump in the water tank has stopped working (no noise, no water no pulsing when switched on and off by the control panel) After ringing auto-sleeper they suggested that I have them fit a shurflow pump under the bed. I cannot find any information on the internet showing how the conversion is accomplished......can anyone help or direct me to a website that shows the procedure?
Thanks
Fred.

Check the fuse in your EC500 first before spending money, did A/S not suggest that first?

That is suprising as it is the most popular topic on this forum (alongside solar panels). Try searching for Shurflo ==>> [You must be registered and logged in to see this link.]

PS You should try Dbvwt suggestion first and check the fuse.

Fuse 4 on an EC500.

My Shurfo packed up after 4 months and like you I theorised why that might have been. In my case I thought it was the intense cold (-3ºC) that had frozen the pump but Willersey who had fitted it thought not and replaced it under warranty. In Jan this year the pump stopped working again. This time it definitely was the cold (-5ºC) as the pump started working again once I had warmed it up which took quite a while. On both occasions the water system had previously been drained down and the pump run dry with its filter removed. The above were the internal temps before we left home.

If you bought the pump from Halfords I would take it back to them for a warranty replacement before you try to take it apart. The Shurflo has a thermal breaker that should reset itself when the pump cools down so in your case I don't think you need worry about its location providing it is in an open space of at least 1 cubic foot as per the manual:

I fitted a Shurflo pump, I also piped it in so it’s very easy to swap back to the original submersible if needed, just two wires on spades and a short length of pipe which is on push fits, takes couple mins to swap back,

The Halfords pump is the spare one, which I fitted on French site, all working ok now. I have repositioned it away from the heater. Old pump tested and runs ok now home, I used my old vehicle battery in the garage waiting to be dumped after 2 years, which still shows 12.5v and never been charged. Did I need a new battery??

by Caraman Sat Jul 22, 2023 5:44 pm

If the Halfords replacement pump worked in France it suggests there was something wrong with the previous pump. The previous pump may appear to be working OK on your bench at home but will it under load when it tries to pump and pressurise the water?

by tbird649 Sat Jul 22, 2023 6:16 pm

My original one ran ok, but didn't pump. I tried priming it, still no pumping, so just because the motor runs on a bench doesn't mean it will work.

by rgermain Sun Jul 23, 2023 11:02 am

Good points. Did not run at all in France, but does now it is cooled down.

So its thermal cutout must have worked but it begs the question why it didn't work on the Halfords replacement if that ran normally in the same temperature conditions.

Just replaced mine which is in the same place, fairly straightforward, as you say a bit of an uncomfortable position to work from, new pump is 30psi so i had to screw the pressure button right down to get the flow right. Hot water tap also came apart at same time so i'm now familiar with the tap switches!

by rgermain Fri Aug 04, 2023 11:17 am

I think 20 psi is about the safe limit to avoid any mishaps. But you seem to have reduced the pressure, so hope it is good.

by FreelanderUK Fri Aug 04, 2023 12:38 pm

Rgermain did you take it back to Halfords for a replacement?

by glyne lock Fri Aug 04, 2023 1:02 pm

Chris
The pump he fitted to replace the pump that stopped working was a spare he had got from Halfords
The pump that was already fitted he had for a long time before he fitted it and could be some of the reason to it having problems
