Why does water run out the low point drains when I turn the water on to the trailer

is your fresh water tank full it could be a overflow or a low point drain

Should be a low point drain near the tank fill area underneath the trailer.

Sounds like it may be a low point drain for winterizing. I would disconnect from city water and turn your pump off. Then open the valve. If only a little water comes out then stops have some one watch it while you turn your pump back on. Assuming you have some water in your tank!! If it squirts out under pressure it it probably a drain and should remain closed unless you are winterizing. If it just drips a bit it may be a drain for the defrost function of your refrigerator. After you have figured all that out,hook back up to city water and check it again. Good luck.

Ouch, How did that happen? First thing is to make sure it can't happen again. Maybe a low point drain from your tank got pulled back up inside somehow. Anyway after you have fixed the cause I would loosen a corner of the underbelly, drop it down and then park with that as a (really) low point so it can drain and air out. If it is not aired out and dried well mold could be a serious problem in the future. Good Luck.

I assume you mean the fresh water tank. These drains can be just about anywhere, but always at a low point.

If you can't contact the dealer or manufacturer for location, look underneath the RV, under the sink, behind removable panels inside, and close to the waterpump either underneath it or in the waterpump compartment itself.

There are usually 3, freshwater tank drain, cold water line and hot water line. Some turn and some pull up. Experiment which is which or try to trace them back to origin.

There should be three low point drains located under the trailer. Two will be close, side by side, to one another. This is the low point for the entire plumbing system, both cold and hot. There will be another single low point drain which will be for the fresh water tank. The low point drains may only have a cap on them or may have a valve installed.

basically you get as much of the water out as possible and add antifreeze to the traps and low points. Getting water out involves pulling the cathode/drain on your hot water tank and changing around the bypass valves so you don't have to fill it with antifreeze. There should be low point drains on the trailer (mine has two) Use only the PINK antifreeze which is safe for potable systems. I would reccomend a search on youtube as there are several good videos. Also you may want to pay an RV dealer to do this and watch first time. Once you know what to do it is pretty simple.
