Dear RV'ers. You all have helped me so much in the last year, and I so appreciate it. I have put over 10,000 miles on my Coachmen Freelander and even took a solo trip this month. Everything is going great, except for one little problem, I can't get the low point drain valve open to drain the fresh water tank. The manual says it needs to be parallel to the hose, but it will not budge. Now, it is behind a drawer so it is difficult to access. Does anyone have any advice for how to get it "unstuck". I have a picture of it but can't figure out how to add a picture to my post.

NO ONE has any ideas for me??? I've tried tapping it with a hammer, unscrewing the little tiny screw on top, spraying it with WD40 and it will not budge. I hate to take my RV in just because I can't drain the fresh water tank, but I guess I'm going to have to.

Success! I sprayed more WD40, put on gloves and viola, I was able to open the valve.

I have a Coachmen 2018 Prism with the same problem. The is a knob in the back wall of the bedroom and it says, "Low Drain Point". Can't seem to find any info in the owner's manuals.

I see water dripping out just below this knob outside and at the bottom of the coach. It is coming out of a pipe. When I run the water it increases, so, might be the drain is slightly opened on the gray tank. However, can't budge the knob. Will try so WD-30.

Any one else has ideas please advise. Thanks in advance.

The low drain is to empty your fresh water holding tank, not much more info needed. Sounds like it's not completely closed, not sure why you think the gray water valve has anything to do with it. They are cheap little valves with small knobs. I replaced mine with a ball valve that has a larger handle. Depending on how it's plumbed it might be getting pressure from the line when you run water and that why it drips faster. My advice is replace the valve.

These valves are also on the water heater bypass pipes. I am always concerned that I will snap one of them off by turning it the wrong way. Once I determine the proper direction, I put an adhesive white label somewhere nearby and draw a spiral arrow and the word OPEN on it.

Low point drains do NOT drain the fresh water tank - that's another valve. Low point drains allow water in the lines to drain - you should have both a hot and a cold drain, in addition to the water tank drain. 3 total. I have a 2015 Prism 24J - the valves are small T-handles that pull up to open. Lousy placement, they are behind a panel in the under-bed storage compartment. They will drain onto the ground. Mine happen to be just behind the passenger side rear dual wheels. ST

My low point drain DOES drain my fresh water tank and everything below it so be careful with your blanket statements.

I had the same fear - plus forgetfulness when winterizing and then not being able to remember if I left things open or closed when prepping for the next trip. I just use a sharpie and draw on the wood near the water heater valves and the linoleum next to the low point valves (since it's under a drawer and out of sight). Very handy!

I agree with loggenrock. The valves called "low point drain" refers to the valves that open the pressure lines and allow the water retained there-in to drain by gravity. If indeed those valves also drain your freshwater holding tank then when you close those low point drain valves the pressure in the lines when the system is pressurized would backfill your freshwater tank. Your freshwater tank has an overflow/vent line so when your low point valves are closed there must be water constantly flowing out your vent line. Right?

My rig has two low point drain valves and one freshwater drain valve.
