I've had this problem with a rental that was always used on hookup/city water. The vent line was installed wrong with a dip that filled with water. I cut the vent line, reran to get rid of the dip and reattached. I bought a used trailer and the vent line was clogged because of mold. I replaced the vent line, cleaned everything and completely flushed and drain the fresh water tank many times.

I'm assuming the hose was going to the fill port, not the city water hookup. No need for the pump to be on.

Thank you

guys not that confusing. he is asking if he needs the pump on to fill the tank. he does not. I think the OP realizes he needs the pump on to draw from the tank. that's not what hes after. sorry for the confusion OP.

Thank you.....

They did however answer part of the question regarding the possibility of clogged valve or kinked hose.....

If you are not hooked to city water, ie hose connected to a spigot and connected to the side of the trailer, then yes, it must be on. The pump will provide the water pressure to move the water from the fresh water tank to the shower, sinks, toilet, water heater, etc.

If you are hooked directly to the "city" water system, the "city" water system provides the pressure needed to move water to the sinks, etc. Just like at your house in the city.

If you have a house out in the country and are on well water, you must have a pump to get the water to the sinks, etc and to provide pressure.

You could have a problem with the water pump.

No it was not, that is part of my question. Do I need to turn it on?

OK now I'm a little confused....

No you don't need to have the water pump on to fill the fresh water tank.
Yes you do need it on to have pressure to your faucets and such IF you are not connected to city water line. A lot of trailers can only fill the Tank with a gravity feed hole with a cap on it (some have an optional valve from the city line but lets work on your fill port since that is what you were using).

Sometimes when filling the fresh water tank through the fill port you can actually fill too fast and create a pressure backup. This is worse if the vent line is clogged (could be as it hasn't been used for a while) this line is a small vent line that might go to the roof, could come out under the trailer, or might be a small screened port next to the fill cap. You may want to try the filler nozzle thing linked to above and sometimes that helps or maybe just slow the water pressure down can also help. The fill line might be kinked or have a bend in it that also slows down the filling process thereby making you think it was full. That line is the one from the fill cap and you will have to figure out what is on the back side of that fill port to know where to look to see the hose if you want to see if it is kinked.
The quantity panel may or may not work. Usually they last a while for fresh water but not so good for Black or Gray. You will have to check once you know you got water in the tank.

Personally I would try just filling it up with a low pressure from your hose and see if it takes water at all, and then turn on the pump and see if water comes to your faucets. You will hear the pump when it operates. Usually right after you turn it on until it builds up pressure (a second or two) and then fairly continuously once a faucet is opened.

Good luck.

Climb under the trailer and find the fresh water tank. Check that the drain valve is where you want it (open or closed). Follow the fill tube to the side of the camper. Check that all is clear of blockage. The pump does not need to be on for filling. Use low pressure (don't turn the faucet full on). Make sure water is getting to the tank. Check the drain valve again. Is it open and draining as water is going in? Close it. Check for other leaks. Once water is in the tank, turn the pump on and see if water will come out of a faucet.

You might need a new fill tube. On mine it is a plastic tube that I could get at Lowe's if needed. Or check with your local RV dealer.

Make sure you sanitize it. I use chlorine dicor (I think that's what it's called) It is for all intents and purposes, bleach. For bleach, I can't remember what the ratio is.

Have fun with it..

It can't pump water when it is off.

To fill the tank?

30Mallard,

Maybe I'm reading you OP wrong. You indicated that the trailer had been on city water for eight years and you found your fresh water tank empty.

You know there are two separate water systems on your trailer? With city water and city water pressure, your trailer is fed water to all faucets and toilet.

If you use your fresh water tank (with not being on city water), you need to turn-on the water pump to pump water from your fresh water tank to all faucets and toilet. Without using the pump, there is no pressure to push the water through the lines from your fresh water tank.

The tank will not fill. The monitoring system shows the freah water tank as being empty. I have tried a few times to fill ot but still will not accept water.
