My kitchen sink is clogged. My son drained grease in it. At first it still drained but slowly, i poured draino down it and it caused it to stop draining all together. I took apart all the pvc pipe and put a 25 foot snake thru. This greasy mud like substance comes out. Ive hit a block but not sure if its the clog or corner. Im at a loss. Disherwasher wont run with it clogged. The snake goes about 10-12 feet in before it hits the block.

The "block' is probably NOT the stoppage if it was caused by the grease. If it is grease, your snake will go through it like Jello, without removing it.

you can try the following 'hail mary'


pour an ENTIRE bottle of dish washing liquid into the sink drain

then 1 quart ONLY of warm water

let sit for 24 hours

if it don't work all you have lost is $2 and some time

If i took the pvc pipes apart and poured draino directly into the metal pipes that pvc pipe goes into will push it thru? Ive been slowly pouring water down the pipe and it still backs up but is draining slowly. Been doing hot water thinking itll push the grease and muddy substance thru with dawn soap

NO Drano EVER

do EXACTLY what I suggested or you are risking serious damage and/or injury

NO acid EVER

you have the proper advice from a retired competent plumber

Drano and Acid Cleaners don't work that well on grease. But I'm sure that now you know that. Enzyemes, work much better. I hope you saved your receipts for the Drano. I'd ask for a refund.

A good word to your son, about the grease, might be a good idea too.
