Will plumber's tape seal a rain barrel faucet?

Rain barrel faucet


Is plumber's tape sufficient to seal a faucet screwed into the side of a rain barrel?

The drip suggests not.  For now, we'll put a bucket underneath to capture the water.  Then when the barrel is empty, we'll use caulk as suggested by the rain barrel workshop instructors.

What you need is a "bulkhead fitting"- such as this http://www.bayteccontainers.com/bulfit34.html

A tapered pipe thread just won't seal, there is not enough wall thickness to do the job of cutting threads.

Does enough of the faucet's threads extend into the barrel to allow the use of a nut and a rubber washer?

uniseal's work better for this application and are cheaper.

I second Eric's suggestion about the bulkhead fitting. I bought one at tractor supply for $7 and my rain barrel faucet hasn't leaked a drop. Well worth it...just need a hole saw to cut a clean opening.

For plumber's tape to work well, you need tapered thread on at least one side of the connection. That will help compress the tape, making it seal.

The wall of a plastic barrel is too thin to support enough thread to make a lasting waterproof connection. And it is not stiff enough to compress sealant tape.

Since you'd have to raise a rain barrel anyway to be able to put a bucket under the tap, I'd recommend putting a bulkhead connector in the bottom of the barrel and putting a ball valve in that. That way you can drain the barrel completely for the winter. And it is a lot easier to open a ball valve completely than to open a tap.
