Every few months my kitchen sink clogs up. After the PVC drain trap there's about 30 feet of 1 1/2 inch PVC that feeds into the larger PVC drainage pipe & out the house. About halfway thru there's a drain tap. When I take it's cap off the pipe is loaded with gunk. How can I both clean this system immediately & prevent this constant backup?

1- Get rid of the lousy PVC

2- Increase the kitchen sink waste line to 2" diameter ( I never use less then 2")

3- Use long radius fittings not the CHEAP PVC short radius fittings

4- Use a 2" x 11/2" trap

5- Make sure this line is properly vented and give it some pitch

Thank you for your suggestions and in a perfect world I would replace 1 1/2 inch PVC drainage with 2 inch pipe. But if you or anyone would suggest a product or method to help keep the existing kitchen drain PVC pipe from clogging every couple months it would be appreciated.

Ok you want a quick way out that should last about a year (depending on usage)??

Call a plumber to WATER JET these lines as water jetting will restore full flow and snaking would be a total waste of time and money.

Water jetting scours the internal piping to a like new condition removing years of build up of grease and soap scum deposits.

How is that for a perfect solution and next time beat the heck out of the installer who would dare use 11/2" line for a kitchen sink

Are there any products or methods that I can use aside from calling a plumber, to prevent these lines from backing up, thanks.

Keep the grease from cooking going down the drain, fill the sink up with warm water NOT scalding hot and let the full sink drain this will keep the trap and related piping much cleaner.

One more thing chemicals that generate heat can distort PVC and installing a disposal on an undersized line was not the greatest idea.

Because your line is only 11/2 and being PVC no less you can expect chronic problems

I don't know much about plumbing except changing things out. My neighbor recommended for me to prevent my pipes form clogging to use lye every week. Don't know if this helps...????

I don't know if I would want to use lye in PVC pipes, especially since you have no personal experience with it. Are there any other good methods or products to prevet kitchen sinks from cloging?

What exactly does a Water Jet look like? Is it a soft black rubber piece of hose that screws into a garden hose on one end & is open on the other end? I think I have one made by "Drain King"

No garbage disposal installed to worry about. However I was told to pour down the drain a cup of baking soda, vinegar, followed by a potful of boiling hot water after 15 minutes once a month. But you say not to use boiling water on PVC, that it will distort it, is that so ?
