“A boiler drain is hard to tear apart,” according to Bob Beall, Pittsburgh’s trusted plumber, offering expert plumbing advice daily through the Mr Rooter Tip Of The Day. “The handle and packing nut will come away easily, but removing the stem from the body,” says Beall, “takes some considerable muscle.”
It will be necessary to remove the drain from the boiler and clamp it in a heavy-duty vise that is securely bolted down,” according to Mr Rooter, the most referred plumber in the Southwest Pennsylvania region, dominating Pittsburgh as the trusted plumbing service.
According to Beall, to further complicate repairs, you can’t use a wrench to remove the stem because the flats are tapered. Only a deep-well socket and long breaker bar will get the stem off. “Replacing a boiler drain is much easier than repairing one,” says Beall, “but if none is available, you will have to fix what you have.”
Mr Rooter Tip of the Day
Tip #1 Start by draining the water from the unit using a garden hose. Then disconnect the hose and remove the drain spigot from the boiler. Lock the drain in a vise. Remove the handle nut and handle.
Tip #2 Inside the nut is the packing washer or stem seal. Replace this washer if the faucet leaks around the handle stem.
Tip #3 Now to the hard part. Use a deep-well socket of the exact size to loosen the stem body. Some stem nuts are standard, others are metric. Make sure to have the right socket by slipping on several sizes, selecting the one with the tightest fit. Attach a breaker bar to the ratchet and apply as much counterclockwise torque as you can. It will take a lot of muscle but the stem will come loose.
Tip #4 Pull it free and check the seal for cuts and abrasion.
Tip #5 Remove the seal-holding screw and replace the seal screw. Reassemble the unit, replace it on the boiler, and refill the boiler, following manufacturer’s instructions for any required bleeding of the system.
