Plumbing questions, answered by experts

No, you should not see water in a sewer cleanout. If you do, it could indicate that you have a block or leak in your main sewer line—which can cause sewage to back up inside your home and potentially flood your yard. Your best bet is to call a local sewer cleaner if you notice any water or sewage around your cleanout.

To drain a broken toilet, place towels or plastic sheeting around the base in case of splashing or overflowing. Next, shut off the toilet’s water supply, usually via a valve on the wall behind the toilet. Begin flushing the handle to remove as much water as possible from the tank and the bowl. Don’t flush the toilet if it’s clogged, though. From there, use a large sponge to soak up any remaining water and wring it over a bucket. 

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.

Yes, pop-up drains commonly get clogged with hair, soap scum, and toothpaste. It is important to know how to properly clean the drain or get professional help to ensure it remains clear and can drain water effectively.

You can often identify a freeze-proof faucet by its structure. Unlike a traditional spigot, a freeze-proof one will include a long supply pipe that extends into your home and connects several inches back to your water supply. Many freeze-proof models also have an extra valve on top of the exterior of the spigot, which is the anti-siphon feature that protects against water backflow.
