Hi,

I have a slow washing-machine drain which backs up like so many others here. We have already had it snaked before and the clog was in the concrete slab between the house and the main line to the sewer. I'm tired of this problem coming back all the time. Then I read the following post on another forum (which mentions that newer machines put out more water/sec, which fits my description). Could someone tell me if they think I'm wasting my time with the enzyme cleaners? Or should I just hire another drain cleaning guy.
Thanks!

"Washing machine drain water contains lots of lint. This is the major cause of clogs in their drain lines. Installing a cap will only cause more of a pressure build-up. The newer washers actually need a larger draineline than the older ones because the pump discharges water at a higher rate. Many new installations have a 2" drain rather than the older 1-1/2". Problem with snaking the line is that it is soft material and the snake can go through the clog and then it re-seals when you withdraw the snake. Try an enzyme drain cleaner such as Draincare by Zep. Enzyme cleaners cling to and eat organic clogs. Follow the label directions, including using hot water, and see if that doesn't solve your problem. Good luck"

Should like it should work based on that re-post but every situation is different

Let me take it down one point at a time.
The buzz word here is "organic clogs". A washer line clog consists of grease from the soap matted together with fiber from the clothes. Fifer is not organic. I do not approve of putting harsh chemicals in your drainage system. And I think enzyme cleaners, such as the one you put in a septic tank to eat up the bacteria are grossly overrated and are unnecessary. ( Please don't put up any advertisements, I'll just delete them.)

Installing a cap will only cause more of a pressure build-up.
It's not a "cap" but a compression fitting. I have had one on my 1 1/2" washer stand pipe for over 10 years with no problems and in all the times I have recommended that one be installed I have never got a complaint back from the user.

This is about the only thing I agree with in the entire statement

WRONG! Snaking is the only sure way that I know of to clear a blockage. With a auger tip the snake will auger into a fiber/grease clog and pull it back.
All in all the statement is just a advertisement and endorsement for Enzyme cleaners and is just chock full of inaccurate information.
