Water line question ?

[crash]

One our last trip this past week end we had a small water leak (drip drip drip )you get the picture anyway it was leaking from the blue line in the front basement hook up area ( 2 small water lines red and blue) with some kindda pop off valve 90 degree fitting then the lines run straight down and out the bottom of the camper,I could push down on the top of the valve and it would slow the drip (it has a plunger type rod in the top with 2 o rings and a saftey type clip on it ) what are these lines for and is it an easy fix.Thanks.

Sounds like the low point drain for the cold side. You can remove that pop off valve, replace the 90 degree valve with a regular elbow and then put a valve at the end of the line.

All the fittings are available at any big box hardware store.

That sounds like your low point drains. They should have caps on the ends. The fix depends on whether the leak is actually in the line or in the fitting, which is more likely. Try to locate the leaking fitting and simply tighten it.

[chuckster57]

If there is enough line sticking out of the bottom, adding a fitting with a cap is an option.

When the pop off valves are used there isn't any end caps as a rule.

No caps at the ends .There is not enough line sticking out of the wall to remove the pop off valve either,where the 90 degree pop off valve is its right up against the darn wall,You can push down on the top of the pop off valve to get it to seal better it just wont stay down enough to seal it by itself If I was to cap the end will it then drip out of the pop off valve itselfWill try and take pictures this evening after work. Thanks

There may be some debris in the valve .... while under pressure, try opening and closing the valve a few times to try to flush it out. The tubing is PEX and any hardware or plumbing supply will have fittings for it. If it drips from the valve itself it may just require tightening of the packing nut. Waiting to see the photo for type of valve ?????

The valve just has a saftey clip that is hold down the plunger from the top(the plunger itself has 2 o-rings on it)Its a 90 degree elbow valve .I will take some pic this evening and post friday.

I think this is what OP may be referring to. This is the low point values on the hot and cold sides of my RAPTOR. As you can see I have a little room to get that main line clamp off that valve I THINK ? As you can see it is close and OP's may be part way in the wall

Sounds like something may be hang up in the valve? Part of the O ring??

[crash]

Those are them,mine is leaking from the blue one.Thanks for the picture PARAPTOR

If removing that c-clip allows you to remove the cartridge and the o-rings are intact, a coat of plumbers grease should stop the leak. Replacing the o-rings would be next or if you can get the exact new valve .... remove the cartridge from the new one and put it in the old as long as the old valve body is not cracked or scratched. .... Just some options to replacing the whole valve. It could be as simple as some sawdust in the valve. (It seems to get into everywhere else.)

Those 90 degree valves are plastic and not really durable. You can buy metal 90 degree valves for about $4 at Lowe's or HD. They are available online also, Here is one link with all the information about the valve. To replace them, just cut the compression ring, pull the valve out of the PEX, install new rings on both ends, insert the new valve and use a compression tool to tighten the new rings. If you don't have a compression ring tool, most ACE or True Value hardware stores will loan you one if you buy the compression rings from them.

Here's the links for the valves and rings:

Thanks everyone for the help.

Now to sound completely ignorant: (Not my first time) Can one of you explain the purpose of these valves? I thought I knew most components of our trailer but not these. Many thanks in advance.....

They are called low point drains because they are at the lowest elevation of the fresh water system. If you open them and then open all the faucets, Gravity will drain the water out.

Many thanks for the info. Just one more little item that wasn't included in our walk-thru.....thanks again.
