Yes, ammonia does damage pipes if used or disposed of improperly. Although ammonia-based cleaners are commonly used to unclog drain pipes, they either come already diluted or instruct the user to dilute them before use. Otherwise, undiluted ammonia is too caustic and could corrode certain plumbing types, such as PVC.

Toilet handles can get stuck for a couple of reasons, but it’s commonly an issue with the chain. Remove the lid and check the chain’s connection, running from the flapper to the handle arm. Sometimes the chain gets snagged on or against another part of the tank. 

The chain might not have the right tension. For example, a chain that’s too short can make the handle feel stuck. Check that there’s some slack in the chain. Old, worn-out flappers can get stuck, too. In this case, you’ll need to see which size toilet flapper you need.

Sometimes when a pipe bursts in a house, it makes a clang or popping noise; however, that doesn’t mean you’ll hear it. Newer pipes tend to be quieter than older pipes. Plus, a pipe can easily burst out of earshot, especially if it’s a floor or two away from you. 

If you do hear an unusual popping noise, consider hiring a plumber to inspect your pipes. Most of the time, you’re more likely to notice a burst pipe either from a visible leak or because water won’t run out of your tap properly.

Low water pressure is the most common problem with showerheads. Whether it’s due to scale and calcium buildup, clogs, age, or damage, poor showerhead spray costs you time and a relaxing experience. If your showerhead is in good condition except for buildup or clogged holes, try cleaning it with a scale or calcium remover. If the showerhead is old, rusty, cracked, or damaged, it’s time to replace it.
