Slow Draining Bathroom Sink - What to use?

[JavaJelly]

Very slow drain. Didn't know if Draino or equivalent was OK. Any suggestions to clear the drain.

Hi Scott - can you get the "P" trap off and check to see if there is a blockage there?

I have used a drain cleaner with plenty of water to flush the pipes clean of it, and I have used a small plunger with equal success.

The plunger also works great for the shower.

I believe I will stay with the plunger until it is no longer effective.

Scott, I would try bleach and hot water before I would use a Draino type product.

Hi Scott,
I wait until the grey tank is 3/4 full. I then use liquid Draino per the instructions. When the drain is flushed, I fill the rest of the grey tank and then dump the tank. Close the valve and put about 1/4 tank of water in the grey tank. Return to normal use.

Checked trap. Clear. Found that the clearance b/w the stopper o-ring and drain was too tight for proper flow. I will try to adjust. However, Has anyone tried getting around under these sinks? It is like Yoga.

Scott, most likely hair and gunk is blocking the drain before it gets to the trap. Take out the stopper by unscrewing the stopper retraining rod from under the sink on the back of the drain and pulling the rod out. Then pull the stopper out and use a bent wire to pull the hair out of the drain. A long screw driver will scrape the rest of the gunk off of the pipe walls.

Home Depot sells a plastic strip with plastic teeth for under $5 that works great for cleaning traps. Just have a strong stomach when you see all the clumps of hair you'll be pulling out. I'm surprised my wife still has any left after what I got last time!
