Shurflo Traul King 7 water pump

[Sarita]

Hi, I am the least technical person I know however 1 week into a 4 week adventure and my water pump has given up. A few days ago it was making a bad noise - I thought perhaps trapped air from the sound. Then water worked intermittently with no rhyme nor reason. Now nothing. No water, no toilet flush for the last 2 days. I’ve turned things on and off, opened the cupboard and taken a photo and that’s the end of my ability. I called loads of repair places and nowhere has any availability so it seems I need to learn! I’m happy to buy a new pump but are they easy for the novice to fit? Can you guide me to any instructions that involve me not causing a major flood and explosion?
Yours in hopefulness (please don’t tell me to check the filter I have no idea what it looks like nor where to find it!)
On the photo one of the red wires on the right appears broken - should it be?

Your pump is a common fit on most things for the leisure industry. The pump has a date stamp on it of 2005. Your filter is on the left . Looks like a little dome shaped thing with a wire gauze inside. The filter looks grubby but that could just be the picture. Turn off your power to the 12 volt system and get some rag and just go for it! There is nothing to worry about. Most of the time its the diaphragm in the pump itself that fails and not the pump motor. The cable you say is broken or looks broken? Its only 12v so it wont hurt if you join it together . Listen and see if anything works?
Does the pump make any noises at all?
If the cable you have showing it broken..can you put a multi meter across it and see if power is there or not?
Loads to do but really simple stuff! Check the power first , then strip the unit from the truck and put it on the bench in the garage and play with it!
A new pump is readily available from most places who deal with the leisure market..so dont just think Motorhomes or Caravans! Boats etc they have the same system.

Try again ?

 

[Sarita]

Thank you Kev, the wire is on the right hand side - looks like it’s been cut but I don’t know if it should look like that?
I have no clue how to turn off the power to the 12V system I’m afraid other than switch the lights on and with for the battery to die!
Do I need to drain the water tank before I unscrew things? I just put little one to bed but in the morning I’ll try putting wires together.
Boat repairers however are genius - I’m in Norfolk at the moment and there are more of them than caravan repair shops
Thank you

Will give you a pm in the morning and try to explain what to do?

 

[Sarita]

Wow, thank you so much that’s really kind

The red wire on the right of the photo has been cut for a reason and has nothing to do with the pump.
It does look like the pump has been leaking onto the light brown convoluted pipe (water marks) below so water may have entered the switch and corroded it.
Probably a new pump required and easy to fit, just two pipes and two wires both of which are obvious as you remove the pump.

As pappajohn states a new pump is an easy fit. Obviously depends on your budget but normally 50 notes. If you pop in to a boat yard they will tell you exactly what is going on and possibly have a cheaper unit for sale too? As regards the cable work ..Seems a little odd that some one has cut it and left it?
That aside..It is an easy fix whichever way you go

 

[Sarita]

I seem to remember when we bought this there was an annoying beep that wouldn’t stop, the garage ended up cutting something so this could be it. If I can buy a pump for £50 and fit it myself that’s a bargain - I am used to getting stung by labour so this is a winner. If I can’t do it (very likely!) I’ll pop into a boat yard I would never have thought of that
Thanks guys

To fit the pump...
If the new pump is the same as the old simply compare the new and old.
Whatever is attached to the old but not the new, remove and fit to the new.
That's it, job done.
The pump is self priming so if you don't know how to turn off the pump swap the wires last as the pump will start once the wires are connected.
You may need a spanner to connect the water pipes... The white nut on the right and the filter on the left.... And obviously a screwdriver to undo the screws holding the pump to the wall.

Control panel may have a button that switches pump on and off. Sometimes has picture of tap on it. If not just press the button on the panel and turn all the power off. A small boat yard would be able to help but it’s not a long job to change a pump. If you happen to be on a site someone may help. As for the pump Amazon do a very good delivery service. We used them in Spain last year .

Have a read of the MH manual or Google the control panel. Lot of foreign vans use CBE panels.

When you get home it maybe a good idea to find out how it all works.

If you want any further advice you will have to pay your £15 as you have no more free posts left.

I have a used spare one if you need for £15 plus postage. Thought I needed a new one (only 2 years old) but it turned out to be something else so fitted it anyway. Very easy to fit.

It is well worth paying the £15 membership to access a huge amount of helpful information and also to be able to secure this bargain!

Sorry if this is too obvious, but you did say you haven't done plumbing before. When you make a screw connection, water can seep out slowly along the tiny gaps in the spiral thread. To avoid this, get a roll of PTFE tape (sold at the same place that sells the pumps, or any DIY store). It's not self-adhesive, so it can be a bit tricky to wrap it tightly round the thread two or three times before tightening up the connection. The PTFE tape deforms and fills the tiny gaps, making a good seal.

Tape shouldn't be necessary in this case - the thread isn't the seal.

I just bought a new Shurflo exactly the same as that one in the picture ( bought from Amazon for £56 and delivered next day). It was a doddle to fit and took less than 10 minutes with a small screwdriver and some mole grips to undo the connections on the pipes which had been overtightened - I was replacing like with like. It came with instructions which very specifically said do not use PTFE tape - just hand tighten the fittings on the water pipes. The water flow is now fantastic and constant whereas before it used to splutter a bit because of various leaks and air ingress I suspect. When I changed the pump I also fitted a new filter ( about £11) as I thought there may have been a hairline crack in the filter.

 

[autorouter]

The picture shows an adaptor, 1/2 inch BSP to push-on, screwed onto the pump body. It's not a compression fitting, with an olive, that tightens round the water pipe. OK, if the instructions state no PTFE tape, I stand corrected.

i` think you will find the op has had their 5 free questions and now gone?
