Leaking Fitting

[mikereidjr]

Good Morning-
I have a 2013 Springdale 26rlssr, I have a leaking fitting on the outside of the RV causing my rug to get all wet and my pump to keep recharging if i leave it on.

Why is one solid and does one have rubber in it? The rubber insert is what has a pin hole in it.

Can I replace it with a solid one?

Thanks!

Those are your "low point" drains used only for winterizing your RV. Many have "quarter turn" valves and no caps, some have "dome shaped" caps and some have "your type" of caps. Anything that will stop the leak is completely acceptable, so if you have something handy, just put it on and you'll be "good to go".....

Why one of yours is solid and one has a rubber insert ???? My 2011 Springdale had quarter turn valves (from the factory). It's possible yours did as well and someone decided it was such a good idea they chose yours as their supply. Then again, it could be that the other solid cap was lost and someone "just stuck something on it" ..... I can't say that I've seen a "rubber insert cap" used on the low point drains before. I'd suppose that "over time" the rubber would eventually deteriorate and cause problems.

I usually pump anti-freeze through the system, I have never removed the caps before, but should I?

It's "more a personal choice" than a "necessity".

My point of view (there are many others) is to remove as much water from the system as possible before adding antifreeze. That way the antifreeze is not diluted and less will be needed to achieve greater protection. By removing the drain caps and using compressed air (at about 40 PSI) almost all of the water in the plumbing can be "pushed out". That allows for "close to 100%" antifreeze solution as soon as the "pink appears" at each faucet.

Is draining the system really necessary? If you live some place with sub-zero temps during the winter, the stronger the antifreeze solution, the greater the protection and the less likely that freeze damage will occur. On the other hand, there are places where winterization isn't needed at all, so depending on where you live and the temperatures you'll see, different "techniques" to winterize will be all that's necessary.
