We have PVC pipe for the waste water in our house. Whenever we run the dishwasher or run the sink in the kitchen, we get a tick, tick, tick, etc. sound when the water flow slows.
I assume this is due to the water trickle hitting the pipe wall. Is there anything that can be done to stop it?
Thanks for you help.

Knocking, popping, creaking and crackling pipes are a common complaint, especially in colder weather. I can tell you what's happening and take the mystery out of it but you're not going to like the repair. When a draw is made on a hot water line the line expands against a pipe strap next to a stud and when you drain hot water from your tub or shower it goes into a chase that is a little cooler then room temperature. The heat expands the pipe causing it to rub against the stud to which it is pipe strapped. This is the sound you hear. As it cools it contracts and the noise is heard again. To repair it you must tear open the walls and locate the pipe strap that's causing the problem and shim it tight. Most people when they learn what causes it just elect to live with it. Regards, Tom

Your'e right, I wish there was an easier answer, however, I very much appreciate the speed of your reply.
