Thread Sealer for Tank Plug?

Mark R.

Thanks for your help. My tank is above ground, however I never thought of the problem with outside stuff getting inside an underground tank. Thanks again, Mark R.

I am going to clean out my heating oil tank (280 gal), and need to know which is the best thread sealer to use on the 3/4" pipe thread when I put a drain valve in the bottom end of the tank. Which is better, pipe dope, teflon tape, or something else? I'm going to use a ball valve so I can drain off sediment etc. from the lower end of the tank. I plan to put a cap on the valve in case it were to be accidently opened. Any comments would be appreciated. Thanks, Mark R.

Millrose 3 wrap

teflon tape with a little pipe dope on top for a little extra insurance. Mark just make sure you get the pink tape by Millrose. This tape is actually tape,not like the white tape you see for fifty cents.

Never use tape ..........

only a good pipe dope like #5 on any and all oil fittings.
If teflon tape is found in pumps returned for failure they will void warrenty. Also be carefull "cleaning" an oil tank,many older tanks will leak after "cleaning".Sludge isn't a good thing unless it's what is holding the tank together. If tank is over 20 years old you should consider replacement and start fresh. With proper water drain off, chemical treatment and fresh oil a new tank will give many sludge free years of service.Also try to protect any valves off tank from something falling and snapping it off. PS I have been told that double wall tanks will be required soon in the Ma and other states that means more $ for all. Hope this helps

underground...*~/:)...

you should get a roll of wonder tape and some two part epoxy ,or a smalll can of grip. then take and clean every thing real well around the welds on the tank,goop up the threads,spin it in, wrap some tape over the pipe and visible threads then mop on some more grip and wrap it to about 6 " above grade...you should also mop any pick point welds,or brass fittings after tightening, this pretty much ensures nothing from outside of the tank will find its way in unless someone puts it in there.. single pipe systems have been installed with out this sealing of welds and wrap of the pipe and threads below ground and the rust begins

this is what the fill and vent pipe looks like after wrapping the outside of the pipe and gooping the base of the begining of the wrap of the pipe. in this picture i am watering the tank to aid in compaction of the surfaces surrounding the tank it seems odd yet no water is going into the tank.

Old Tank?

If it is old enough to need cleaning I would suggest replacing it. I've seen them start to leak after they are poked & proded.

I am in love with Loctite 567, thanks to heatboy for showing it to me. Have never had a leak yet, no more teflon, and messy joints. Just be careful, because this stuff is not for use on plastics.
