My toilet bubbles when my washing machine drains, and water comes from under my shower. I am on septic.?

Your problem needs a lot more information to give a definitive solution. If your field is flooded your gray water really has no where to go. It won't and can't go into the field. It's already clogged with water.When you empty your washing machine it overwhelms the system that is partially blocked.(by water or roots or an object in the line) the results will be bubbling in the toilet because of the backup. Neither your toilet nor your shower is protected by a back flow valve? The lowest outlet, toilet, shower or drain will allow the water just flushed in to back up into the house. Water runs down hill. Is it spring time in your area with and the flooded?

The fields will become clogged with undisolvable waste particles over time. This makes it unable to continue accepting more material to dissipate. Clay for example plugs up much quicker than sand. I've seen a lot of new products that claim to open up the fields by breaking up the soil and making it like a new system. I'm a little skeptical on this one.

Sometimes the septic tank becomes clogged. The only resolve is to get a sucker truck to remove all of the tanks product and begin anew. This also is a temporary solution. I've heard of a lot of people getting another 20 years of service out their system with this solution.

Another problem is root inclusion. Roots begin growing in earnest when the leaves fall. That's why most of the rooter guys are cleaning sewers of roots between about October to March in the Northern hemisphere. In the spring when the leaves begin to emerge the roots stop growing and unless the roots are already clogging the lines at least partially your problem won't show until fall.

There are products like rootx that if applied when the roots are first, cut ,within 24 hrs) that seem to prolong the time until the next blockage. These occur in both septic systems and city sewers.

Therefore, find out what is causing the back up. Is it flooded or clogged fields? Is it a blockage in the system,, the tanks or field that is unrelated to flooding? A flushed toy? An extremely large percentage of the clogged systems are by used sanitary napkins being flushed. They absorb a lot and don't dissolve in a hurry. You don't want a temporary solution to this problem. Get a competent sewer cleaner to evaluate your problem and fix it. I've heard that the baking soda , yeast and a plethora of other solutions help get over some of the humps. If it works for you...great.

the septic tank might need pumping out.

You could try introducing a bacteria to help eat away the septic tank material.

I know there are some specifically for this but one old septic tank pumper that we had suggested getting a bag or big jar of yeast and flush it down the drain with a bunch of water at night so it is not disturbed for a few hours.

It worked for use and helped extend the time between pumpings.

Of course all this was over 20 years ago so if yours is a more modern septic system, it might work differently and you might need to call an expert.

Yeah I agree with ckngbbbls that you may need to have your septic tank emptied, they do need to be done every now and then depending on many people in the house and the size of the tank.

I am sure you are aware that you need to be careful what sort of chemicals you use, in a septic tank, as some chemicals kill off the bacteria needed to make the septic tank work.

Before moving into to town I was lived for over 40 years on a farm which had a septic tank, and its not a pleasant job to have the tank emptied, but thankfully we only needed to do about 6 times in that time.

Time for a pump job sounds like to me.

maybe you should snake the toilet or where the washer drains sounds like a clog somewhere
