Plumbing questions, answered by experts

Plumbing repairs cost $180 to $500, depending on the scope and urgency of the issue. A knocking pipe is usually caused by a problem with the water pressure or air pockets, so the costs will likely fall closer to the low end of that range. Pipe replacement will likely cost more than that since it’s a major project.

Knowing which type of bathtub faucet you have is the first step toward finding a replacement. The faucet can be deck mount—meaning installed on the tub itself—or wall mount—meaning installed in the wall. Some bathtub faucets are freestanding and installed on the floor. There are also single- and double-handle models. Some faucets have a diverter on the spout to move the water from the showerhead to the bathtub spout, while others have a third handle that acts as a diverter.

The type of sealant you use on a leaking pipe will depend on the pipe material and the cause of the leak. PVC P-traps should avoid petroleum-based sealants, which can degrade the plastic and worsen the leak. Pipe sealant is specifically designed for use on pipes, but remember—if your P-trap has a crack–it’s best to replace the pipe to avoid future leaks.

Flushing a water softener is another way to refer to a thorough cleaning of the system. The process involves several steps, including disconnecting electrical power from the system, physically draining the water and salt from the brine tank, scrubbing away deposits, putting the system back together, and performing a regeneration to clean the resin and resin tank.

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.
