I think the main drainage line is backed up. Can I use Liquid Plumber [View all]

on several drains throughout the house to see if that could solve the problem?

It started when many loads of laundry, with tons of cat and dog hair, were being done. This is way more than I used to do by myself before I rented out the little Mother in law part of my house.


Anyway, stuff is backing up into my shower and now hers. And the toilets are getting backed too. We've been able to unclog them and as long as you don't use the washing machine.....so far......things seem to be OK.

I was thinking of getting several bottles of Liquid Plumber or whatever and putting them down several drains at a time, (sink next to washer which I forgot about and the other 2 showers, the kitchen sink and both bathroom sinks) and seeing if that would reach the main drain and dislodge things. Maybe repeating this several times.

My house is small.

I read about the prices to get the main drain snaked and I am afraid!!!

Any ideas would be greatly appreciated.
