help with leaking valve newbie

From your picture, my concern would be that you have water on the bottom of the trailer above the two drain valves. That would indicate that you have a seepage in a connection somewhere upstream. You should trace the lines inside the trailer and find the leak. Then as was mentioned, replace the leaky connection with sharkbite type. You should have enough play in the lines to cut the old fitting out and install a new one. If you use sharkbites, just make sure you cut the tubing square, using cutters, not a hack saw.

jeesh this forum is great thanks for all the help fellas! got a picture of it on my phone so i'm planning On going to the local RV place here after work and swapping them out for something else....on a side note after I get this fixed, where else should i look for leaks etc after the system is pressurized with those fittings being fixed.....i know the norm is under the sinks etc...anywhere else you suggest?

YEAH..older rigs used valves.
Then 'efficiency', 'productivity', 'cost savings' etc. and caps/plugs became the norm.

Those low point drains just need to be tightened and IF still leaking you can always replace with a couple of valves from hardware store.

Home Depot carries 'Sharkbite' which are really good quality and just snap on (Lowes carries similar but called Gatorbites)

Good old normal low point drains....the white one looks like someone changed the fitting..to something after market...it doesn't look original.

but, all my low point drains have been two different colors..red for the hot line and blue for the cold lines.

Thanks for the reply fellas. From my research I've been doing it looks like they're hot and cold water drains for winterizing. Was just wondering if there was a better way instead of te cheap plastic that is currently on there.

Is this normally how low point drains are? My 20 year old Jayco has convenient valves in the bottom of the bathroom vanity for the drains. Unless someone added them on.

Low point drains. Try removing the caps and use teflon tape to seal the threads. Tighten back up using 2 wrenches
