was the trailer winterized? on my trailer the input line of the water pump is disconnected to feed antifreeze into the system. my strainer is located there too. my strainer cover threads on and needed tightening. check those connections.

you can run the pump with your finger over the input and check for suction.

Apologies in advance, as this will sound really dumb, but did you remember to switch the input valve the last time you disconnected from city water?

There is a sediment filter between the fresh water tank and the pump. Verify that the filter is clear, clean,and not leaking. I have a 69. The two valves control the fresh water drain, the other allows you to refill the fresh water tank from the city water line. Make sure you understand how these valves work prior to trying again

I disconnected input line to the pump. I hooked up the hose I use to winterize the lines to a bucket of water and the pump worked fine. I also checked the filter and it was clear. My next stepis to reattach the input line and try again.

I am at a loss. I reconnected the input line and started the pump. It still sounds like it is trying to suck in air. Could I have a hairline crack in the filter? Is there a value that might not be all the way closed? Could I by past the filter and see if that works. As you can see my frustration is growing.

Again thanks for any assistance or suggestions

Pump runs but Starving for Water

Sounds like you have some sort of blockage between the tank and the pump. My Caravel did what you are experiencing. There was an iron elbow in the line which had rusted inside and plugged itself. I replaced it with an ABS elbow. Problem solved,,,,,forever.

Some water is getting through but just not steady flow. Could a partial blockage cause it or is there something else I am missing

I just read all the posts again, sorry you are having a rough time of this!

Any chance that your tank had water left in it over the winter and is cracked, or maybe a fitting at the tank's discharge cracked over the winter? If the drain with the broken handle is the tank drain, and it was not drained for the winter, this could have caused freezing and cracking somewhere.

What you call "a leak in the pan" could be the possible leak above, finding its way through the corner of the pan? Remember the pan is just a cover to protect the actual water tank from being damaged by impact from road debris.

I would fill the tank again, and don't do anything else.

Does water still drip as you described above?

I don't think you can see ALL of this run of plumbing from the tank to the pump, so it sounds to me like somewhere there is a problem crack etc. in this hidden run of pipe.

PS -- when you winterized the trailer last fall, did you disconnect the water intake/supply line to the pump, and blow (by mouth) back into that supply line to force water back into the tank, from which it would exit via the tank drain, after you raised and lowered your tongue jack to its extremes to force water to leave from the bottom of the tank (by gravity)?

If you did not do all of this, you probably left some water between the tank and the pump, and have a crack in those plumbing lines/elbows/etc. -- most likely a 90 degree elbow right where the water leaves the tank IMO. I had the same thing happen in the 90's at the back of the hot water heater after a hasty on-the-road emergency winterization. These plastic elbows are more brittle than the plastic plumbing lines, and are more apt to crack.

There is the possibility that there was left over water in the tank but I am pretty sure there was no water in the lines as I pump a signifcant amount of antifreeze into them. I agree i am not going to be able to see all the pipes but where I can see there is no water dripping or wet spots. I am now going to see if I can replace the broken drain handle. If this does not work I will be doing dry camping in the strickest sense of the word. Unless of go to campsites that provide running water.

Again thanks for evryones assistance and advice.

When you use the pump to pump antifreeze from a jug, you do NOT get antifreeze into the line between the water tank and the pump. That is the line I was asking about. You seem to have missed my point. Please read the PS in my recent post. Did you do all this last fall when you winterized?

Unless you put the antifreeze directly IN the water tank (not recommended), you probably have a weak link in the chain of your winterization process.

I believe that is waht happen water remained in one of the lines and there is a crack in one of them. Not sure what my next step will be. Might have to takeit to Colonial for repairs.

I have read that the outer pan is not that hard to remove, so you might crawl under the back end to check it out. Once the pan is dropped, access to the suspect area should not be too difficult IMO, and the tank discharge (and cracked elbow?) should be right there. There are other threads here about the visible valves in the back (tank drain etc.), including replacing them etc..

Did you check the voltage at the pump, low it can move impeller but not get enough to pump.

There is no impeller in this type of pump. It is a diaphragm. The OP stated the pump works fine when sucking thru the winterizing source.
I would run a temporary line directly from the tank to the pump intake.
