Rated 5 out of 5 by from Awesome and effective I used this at a clinic where work. The bathrooms get a lot of use and often clog up. I was impressed with the effectiveness of Liquid Plumr industrial strength.

Rated 5 out of 5 by from Works when others don't I had a bathroom sink backup. I went to Home Depot and they had a new green liquid product on sale that was supposed to be the best. Nothing. Went back and got my favorite Industrial Strength. I let it sit overnight, and followed up until the bottle was empty. Took some time but still working great months later.

Rated 4 out of 5 by from The industrial strength liquid The industrial strength liquid plumber has saved me a few times. Just pour it into the toilet and let it sit for a bit, then flush. It’s breaks down the clog and let’s it flow. Works great on Mitchum and bathroom sinks for mild grease build up and hair as well.

Rated 4 out of 5 by from Tried this because the bathroom sink was running slow. It did the trick. Tried it on the sink even though it wasn't running slow. Oh yes I guess it did need it. I will admit I heated water and poured down the drains. Yes I would recommend it

Rated 4 out of 5 by from Industrial Strength Better Than the Professional If you have a slow moving pipe in my shower, the industrial strength Liquid Plumr is the way to go. It is stronger than the Professional strength (gold bottle), though both are price similar. after pouring about 1/2 bottle, I usually leave the gel in for about 30 mins before flushing with a gallon bucket of hot water. I have tried using warm water but it doesn't do the job.

Rated 4 out of 5 by from Liquid Plumr Industrial Strength Beat Drano 1,000x My recommendation is: Do not bother with the regular Liquid Plumr, go for the stronger concentration of the Industrial Strength formula the first time, it would solve most, if not all, clogging/slow drain problems. At Lowe's in NYC, the smallest bottle costs around $5,79 (a bit more expensive than the regular strength).

Rated 1 out of 5 by from Money down the drain I bought based on the marketing: Industrial Strength Gel. I figured... "Industrial strength, must be better than all of the others advertising commercial strength/grade!". I was wrong. After using the entire bottle as per directions, I still have a drain that doesn't really drain. Sorry, not satisfied. It's also not something I could recommend.

Rated 1 out of 5 by from Disappointed. I started New Years Eve with a backed up toilet. I started plunging the toilet and the shower drain and tub drain started to back up. I plunged the shower and the toilet went down, but the shower had overflowed. It was nasty. I put Liquid Plumr in the drains as instructed and waited 15 minutes. Nothing except this white milky substance on the floor of the shower. Still can't use the toilet or the shower or the tub. Guess I'll have to get a real plumber.
