Shurflo pump

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.

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.

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:

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??

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?

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.

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.
