Where exactly do I pour this? In the drain by the washer which backs up or the main drain that the Plumber snakes?

Asked by: Mimi
You can use Main Line Cleaner in either drain but it is best to pour it in the drain closest to the clog.

can I pour instant power main line cleaner down the washing machine drain?

My washing machine backs up into the tub can I pour this directly into the washing machine drain?
Asked by: duca
Yes, you can use it in the drain behind the washer, that's usually between your hot and cold faucets for the machine. I guess the people above think you want to pour it into the washer, but yes, you can pour it into the drain. remove the drain hose from the drain, and pour directly into the drain.

128 oz. Main Line Cleaner is rated 4.3 out of 5 by 236.

I bought this after having a main line clog that was backing up my kitchen sink, shower, toilet and bathroom sink. I was skeptical as a plumber AT Home Depot told me that the only thing that will work is a big professional drain snake. I poured the first bottle down the shower drain and waiting 8.5 hours. This did not clear the clog. I poured boiling water down the drain, then ran hot water for a few minutes and it filled back up. I then poured a SECOND bottle down the left side Kitchen Sink drain. I let this sit for around 11 hours. Worked perfectly. The clog was gone, all drains worked normally. 100% worked on a tough clog using 2 full bottles.

I had my septic tank pumped out and looked in the access hole where the septic tank discharges and water was running back into the tank and not discharging. I probably over did it but when your septic tank is not working no one is happy, I used 4 gallons. after pumping the tank out I slowly poured one gallon in the access hole downstream of the septic toward the lateral lines, I waited overnight and poured a second gallon in slowly. I noticed the liquid was running out to the lateral lines the correct direction. I applied the other 2 gallons the next 2 nights before bedtime while the septic tank was still not full. Its been about 3 weeks and everything is working well.

Thought I would give this product a try based on reviews. I purchased 2 gallons and poured them down the shower drain, as I had a pretty good idea where the clog was and I thought that 2 gallons would attack the area properly. After a 12 hour sit, I poured 3 gallons of boiling hot water down the shower drain. After hearing a quick "glug, glug", the drain seemed to free up and drain properly. I ran another several gallons of water from the shower. Then I flushed the toilet. No problems! Sure beat the $200.00 I spent the last time it happened hiring a plumber! Great product! Give it a try before you spend the big bucks.

I used four other Brand Name drain 'cleaners' to no avail. An overnight jug of Main Line Cleaner in the floor drain and all the house drains are clear. And now for over a month are still draining like new. THANKS MAIN LINE CLEANER.
