Water Supply 2004 T-1950

Anne and Jim · 08-17-2013, 08:11 AM

Having 2 probably related problems. Both occur while connected to water supply:
1-The fresh water tank gradually fills by itself over a period of 3 - 4 days.
2- The water pressure is good everywhere except the kitchen sink and spray hose. There is but a good trickle from the sink. (Using hookup pressure or pump from fresh water tank).

I have taken the screen off the sink outlet, but it makes no difference in the flow.
Does anyone have any suggestions for repair before I start tearing into the plumbing??

Thanks for any help, JIm

Just replaced one in the house for the same reason, diverter valve inside the fixture for the spray hose is toes up.

check valve by water pump is allowing city hook up water to seep into fresh water tank

I agree with Jim. Check the pump. I had a similar problem, but I replaced my overly noisy pump with one from a parts camper, and then the problem disappeared. I chalked it up to a weak pump, but since I replaced it, the water tank stays empty unless I fill it on purpose.

Thanks for the replies, will delve into this problem as time permits.
Looked under the sink and bed yesterday. Did not see any obvious problems. Trailer was over 100F, so didn't spend a lot of time. Is there a schematic available that shows what position each of the on/off valves should be in?

Anne and Jim,

Let's take the easier one first. The fresh tank filling itself. This is as was said, the check valves "inside" the water pump are leaking back through and into the tank. You cannot see these valves outside of the pump. They are internal. To fix you have to rebuild the water pump or buy a new one. Odds are high a piece of hard dirt was stuck in it and may have scratched the valve seat. Having dealt with this headache of loosing pump prime, rebuild it or replace it.

The kitchen faucet. You mentioned a sprayer, unless it was a high end option at the time when the camper was built, this may be that someone upgraded the standard faucet that Sunline put in on day one. Most (not all) did not have a sprayer. If you still cannot get this to work, please post a pic of the faucet and ideally a name of the faucet. Is this a mono lever faucet?

If this was the standard Sunline faucet used in 2004, has an on and off knob for both hot and cold, above the screen in the aerator at the end of the faucet there is a white plastic water flow restrictor / diverter that had lots of very fine holes in it. It is above the screen and will not fall out on it's own most times, have to pick at it. Mineral deposits from the HW tank end up clogging up the little holes. I have has this happen from time to time.

You mentioned valves and which way should they be pointing. H'mm OK here we need a picture of what you are referring to. The normal "valves" are on the hot water heater or the low point drains in the camper and have different needs. Which ones are you refering to?

Hope this helps

John

There are two check valves in your water system one is on the city water side the other is inside of the pump. The city valve keeps the water from running out the fitting when you run the pump. The other one in the pump keeps the city water from filling your fresh tank. As JohnB said about the only fix is to get a pump rebuild kit or replace the pump. They make some very nice pumps now that are quite quiet.

Update: 8/28 Thanks JohnB & mainah.
1. I agree that the check valves inside the pump need to be replaced. I am having difficulty in finding a kit specifically listed for my Shurflo #2088-422-144. Will probably remove pump & take to RV supply to match up.
2. My kitchen faucet is a single lever with attached sprayer. I took the aeriator assembly off of the spout, but there is still very little water flow. My theory now is that there is a problem with the facuet itself. Will remove it in the next few days & check it out.
3. Re the misc shut off valves, I found a diagram, and they seem to be OK.

Anne and Jim · 09-08-2013, 12:17 PM

Update 9/8:
1. R & R pump, disassembled, cleaned all parts. Will not know if problem is solved 'till our next outing. Do not consider this to be a major problem, as it takes 3-4 days or so to fill fresh water tank.
2. Completely removed sink ass'y from counter. Dissasembled faucet, found diverter piston & seals to be "crudded up". Cleaned all parts & reassembled. Now have great water flow and sprayer works fine with running pump. Should be just as good or better on city water. Perhaps diverter valve was dirtied up from lack of use.

Being a smaller guy and semi contortionist really helped on this project, but am sure I will be sore for a couple of days.
Thanks again to all for your suggestions............ Jim

Sounds like you have a good handle on it now.

"Completely removed sink ass'y from counter" H'mm that and this "Being a smaller guy and semi contortionist really helped on this project, but am sure I will be sore for a couple of days."

Ah yup, if you went in under the cabinet to get at the faucet hoses they seem to be in the most difficult spot... Crawling through a drawer opening to get in, I can feel it just thinking about it. .... Been there and felt that....
