Hi!

Great forum!

Our oil tank for the furnace has a shut off valve on it (bottom of tank) that has a slow drip to it from the valve stem which we catch in a small container. I'd like to fix it but I'm wondering how is this done? Seems that the oil left in the tank (there is 1/8 tank left) needs to be drained/siphoned out. Does anyone know how this would be done?

TIA!!

Tighten the nut around the valve stem to stop the leak.

Thanks for the reply....yea already tried that...still leaks. I probably need to remove the whole stem assembly and replace the washer or whatever those type of valves use to seal the unit. Or just replace the whole valve but in either case the oil needs to be drained I guess.

Turn the valve off. Remove the packing nut. If there is a brass "follower" bushing under it, lift that also. Install additional packing, replace the follower, and then tighten the nut.

HJ,

I've never replaced the packing material just the washers....so I was thinking I had to remove the whole cartridge/stem. But thinking about it I can just take off that packing nut and still have the valve closed. I'll try that this weekend for sure! Thanks!

Just try tightening it a little first. Only repack it if that doesn't work.

There is a way to change out an oil tank valve without draining the oil from the tank... even with a full tank. It's a two man job, requires some skill, and there's a risk of damaging the tank if not done right but it can be done.

But try what has been suggested here. It should take care of it.
