Water Pump Question

[daanderson]

I have a 73 tradewind. My water pump stopped working yesterday. The light comes on on the control panel but nothing. My pump, located under the sink is an old pully and belt type. Am I looking at the right thing? I checked the fuse and it's good. Any suggestions?

Check the belt first to see if it jumped off. If the belt is OK use a test light or volt meter to see if you have 12 volts across the 2 wires at the pump when it is on. If you have voltage not sure if you can get to the pressure switch to jumper it out. If you can jumper out the pressure switch and still don't have a pump its time for a new pump.

Mine has a second fuse located behind the control panel also. I won't tell you how long it took me figure that out either.

The 2 wires that feed the pump from the switch have bullet connectors on them near the pump , make sure they are both connected.

Thanks Guys! It was working fine and just stopped. I'll be busy tonight checking everything out. Hope it's a simple fix but if it's like the boat, cha-ching!!!

Are there service kits available for the Jabsco Par Model 36800-1000 (belt & pulley) water pumps?
Thanks

I had my Jabsco Par diaphram fail on a caravan last month. Camper's World did not have any repair parts. I bought a new Flowtec for about $60 from them and it works much better that the Par and fit in easily since it is smaller and less noisy. You might check Vintage Trailer Supply if you want to stay original.

I was to say..."What nairnchyz and dwightdi said~!"
If you rebuilt, so much the better..

The trouble with replacing the actual pump parts is that you are still stuck with the old 12 volt motor...

The commutator in the motor wears with use as the brushes rub against it, and isn't as efficient as it was when new...

If you can swing it, look into replacing the whole pump with the newer, variable speed type pumps...they more efficient, quieter (for the most part if you isolate them properly) and push more water...I did just that and I'm pleased with the results!

Check the high pressure cutoff switch also.

I replaced one in my old trailer. Boy did it make a difference. I put the newer style pump in. Very easy to do

I had the old pulley pump in my first trailer and it worked well but had low pressures and was noisy. I have the new Flotec in this trailer and recently cleaned and bench tested. It pumped great and is very quiet. Mounts in very little space. I like it.
