Water heater drain plug? Trailer about 21 years old.

Trailer about 21 years old and I have never removed the plastic drain plug on my Atwood water heater.  Do you think if I remove that "nylon" plug and flush out the water heater I will be able to reinstall plug and have no drips??  I just completed a kitchen faucet replacement and luckily had no leaks.

  • Yes I think you will be able to remove the nylon plug and even more importantly reinstall it. As said put a bit of Teflon tape on the plug to help seal it if needed. Also don't go monkey tight on the plug. I usually install my nylon plug by hand and  then about 1/2 turn more. If it leaks just tighten a bit more. 

  • you can buy brand new ones in most hardware stores that have rv supplies, like three bucks for a pack of two.  

  • I removed all my low point drain plugs and replaced with valves. Much easier to open/close and no tools required.

        By my way of thinking, it would seem to indirectly indicate you could but a valve on your water heater drain also. But that’s just me.

  • If it drips just put a couple wraps of Teflon thread seal tape on it. Or buy a new one, they’re pretty cheap and readily available.
