Re: Drains Technical Question
Plumbing codes call for a gap between potable water and a drain. This usually looks like the distance between the faucet and the top of the sink or bathtub (one inch or more). Without the "gap", waste water could siphon back into the drinking supply. This "does" happen in situations where a city main is shut off causing a drain-down of the system with plumbing that has been done improperly. Sometimes it is a hose left in a mud puddle, or maybe a hose lying in bleach water. People have died this way. The plumbing code helps protect the general public from these dangers. Current improvements include antisiphon faucets for garden hoses, the air gap for the dishwasher, proper installation of water heater T&P relief drains, and backflow preventers for irrigation systems.

try by taking of the trap under sink, and clearing it out ! its the U shaped pipe under sink drain. this is where most of the sinks plug up. unless you have a plugged up drain pipe. do the drain trap first. if this does not solve all of problem, put some good drain cleaner down sink drain. good-day ! and have a merry christmas.
With regular care, aclogged sink drain can be avoided. However, should this situation arise, tryclearing the drain with ordinary baking soda and vinegar. Use a plungerafterward to add air to the drain to clear it. This usually is the first lineof defense for clogged drains. If this doesn't clear the drain, you may needone of the chemical drain cleaners available in most hardware stores. Today,drain snakes are also available for household use. These can work to cleardrain up to 25 feet along pipe lengths. <br />

Your drain is probably OK. The disposal is going bad. You can temporarily repair the disposal by using plumber's epoxy putty ( found at most home centers for about 5 bucks) to seal the hole. Sand the area around the hole first, and then dust it off. Use about a golf-ball size section of putty to seal the hole. This is not a permanent fix, but it will get you by for a while. Replacing the garbage disposal will be the ultimate fix.
If after repairing the hole the sink stands full of water, then you know for sure that the drain is backed up.
Take a look under the sink. The mechanical pop up has likely become disconnected from the rod that goes into the drain to control the pop up plug. You should be able to just reconnect it and the drain should work fine. If this doesn't solve the problem please let me know. Please remember to rate this solution, your feedback is important. Have a great day.
If you have a wet dry vac, remove all the water in the sink. Then take 1 full cup of baking soda and 2 cups of white vinegar. Pour the baking soda into the drain, then pour the vinegar on top. Let it sit for about 20 minutes, then flush with scolding hot water. If that doesnt work then do it again and let it sit for longer. Baking soda and vinegar make a acid that will eat through most anything that goes down drains.
You most likely have cast iron drains.They work fine for 20 or 30 years or so. Then they rust from the inside out, they scale up sometimes to the point that they close completly off .My point is that any grease or food matter that gets in the drain can stop it up. the quick fix is to run a drain snake throught it then after you get it to drain you might use some professional drain cleaner to further clean out the line. If I'm correct about your drains, you ll need to replace them in the near future.
The small disk right under the strainer is adjustable and has a lock nut. You will need to try and adjust this. If it doesn't work, the I would sugest replaceing them. They aren't that expensive plus they are easy to replace. Good luck!
You can purchase a device from Home Depot that will clean out the drain. In the plumbing business, we call it a blow bag. But some call it drain dog and so on. It's a black rubber bag that fills with water and then when it reaches a certain pressure it blocks the drain but runs water through it until the clog is dislodged. You attach it to a water hose and push it into the drain as far as you can get it. Run it for 15 to 20 min. and then pull it back out. There are several sizes to accomadate the pipe size. You sill need the one that does pipes up to 2 inches. You will have to remove your drain assymbly under the sink to do this. While you have the drain assymbly off, you can make sure it is clean as well. This will clean out the garbage that collects in the pipe. Hope this helps.
