Thank you for posting. I had a seized pump when arriving at the caravan, more than one thousand kilometers from home (and tools). I’ve done it almost exactly as you did. Difference in procedures: I kept the original cable as long as possible and I was using a hairdryer for warming up the connection. It’s been working flawlessly for three weeks already.
Tip for thrifty DIY-ers: I've just fitted a non-Thetford pump (Comet brand, from Ebay). It looks identical to the Thetford pump apart from the markings, made in Germany, so I suspect Thetford buy the part from Comet with their own branding on it. The Comet pump costs about 1/3 of the Thetford pump and comes with plenty of cable, so I was able to feed it through the grommet and make the crimps on the dry side near the PCB.
Great advice, thanks, The cornet pumps are a full pump install thats why the cable is so long to connect to circuit board, or connections like you suggested. And the glue heat shrink will protect in the wet side anyway.
I am about to replace my pump because it periodically seizes. In my Thetford cassette (not sure of model) the electrical connections you made would be in the fluid, so will have to modify the approach. Thanks for posting.
@Robsmixedvlogs I had a hell of a time getting the pump out because the hose was so hard it was that hard to bend that the other end that goes into the toilet ended up popping out when I was trying to bend it out which made it easy and while it's out I think I might put a new hose on it, but from that accidental experience of the hose coming out at the toilet end first I'm wondering if it would be easier to get the pump out by removing the hose from the top where it goes into the toilet bowl first all the time, my main problem is I can't see where the pump sits when I go to put it back in, I don't know if there's a cradle it sits in, which way around it goes, or does it just hang in the place it came out of, is there a special place made for it to fit in and is there a right way around to fit it, when I got the pump out the impeller was jammed so I loosened it and it's working fine again I think I'll give it a spray with WD40 or silicon spray and give it a good work out before I put it back in. Thanks for your video. PS. I've looked at a lot of video's and haven't found one that tells me where and how the pump sits when it's back in place.
Hi there, glad you got to fix your pump. Theres only a grove slot the pump goes back into. Just hold the bump back in the corner and you will find at a point it slides back down. Theres nothing thefe that holds it apart from the stiff hose lol.
@@Robsmixedvlogs Thanks for the info on reinstalling the pump that was my main concern but it sounds like you put it in to the corner wriggle it around until you find a spot where it drops down and that's about it, I might have a go tomorrow without getting a new hose that's more flexible if the hose holds it in position.
@@Robsmixedvlogs I put it in with the old hose this morning and it's working perfect, first I put the pump in position which was easy without have to bend the hose to get it in there, I just got it into position then pushed the top piece back into the toilet and job done, thanks again for the info I needed. Cheers Chappy.
Its the wires and heat shrink that come with the pump replacement kit, the heat shrink is the glue one and it does keep the water out have done more than 100 and no issues at all, I did it exactly how the manual tells you to do it. But thanks for the input
@@Robsmixedvlogs No worries. If it’s the only option but a bit of silicone inside the heat shrink at least. But no I a have not done 100 with no problems so sorry for having an opinion that is clearly incorrect. I guess crimping Vs soldering in a wet area is much better as well should last for ever. Good video though thanks for posting much appreciated.
