First of all I have 2 questions. Just a little over a week ago I had a American Standard Cadet 3 toilet installed by a handyman. Toilet flushes OK so that's good. Two days later I see water on the floor under the tank near the new flex water line. Checked line and it was tight. I then checked line constantly with a papertowel to see if I could fine any water leakage from around the screw nut. Found none. Then 4 days later water again. Now it's been 4 more days and I don't see any puddles on the floor. I don't think that this was cause by sweating of the tank either because it was dry. Where could it be from and why not a continues issue? Afraid someday I might walk into and see a terrible mess.
2nd problem is large bubbles and soap (I used too much that day) came up in the bowl when the washer was used. That sounds like a clog in the drain somewhere. It's like the pipes can't handle all the washer water and it backs up in the first availableway out. I do need to check clean out to see how water rushes through but that's hard to do when I'm only one person. My husband is out of town...great timing. I don't relate the water on the floor with splash out from washer soap because I only did laundry once and the water issue happened twice days apart. I am on septic with only 2 family members. I have it cleaned out every 3 years, mandatory where I live. It was done just last fall. Had someone check vent for bird nest, etc. They didn't see a problem but I'm not sure how good they looked. I would rather stay away from the expense of a plummer but if all else fails I'll make the call. Help!!!

Your washer water should not back up into your toilet. If it does, it means you have blocked sewer line and you need to clean it.

The small residue of water you have found behind the toilet may be related and may have come out of the toilet while you used other plumbing fixtures in your house. It came out of the base of the toilet when rising water column reached wax ring.

Thank you for the info it was really appreciated. So you believe it's a drain clog instead of a vent problem. I called a local rental store and I can rent a 50ft. plummers snake (not sure that I would need that long) for $25.oo for the day. I'll go tomorrow and get it since you think that it's a clog. I'll go down the washer line and bathtub. I'm pretty sure they all run into one line wouldn't you think? My basement is just a dirt floor crawl space so I'd rather not have to venture down there. I'm not sure what I would be looking for anyway. But I can get to the clean out on the outside of the house with no problem. It looks like I will be a busy one tomorrow. I'll let you know how I made out. THANKS AGAIN

I did do laundry and again I had the small leak back. (No soap bubbles this time backed up in toilet) I know for sure that the water is coming from the top of the water line and not seeping out from under the toilet bowl (wax ring). Even though the flex line is new it may I guess be defective. I do know that it was hand tighten to resistance then a added 1/4" turn with a wrench. I know that's the in coming water to toilet and I have problem when the washer water discharges. Is it cause by pressure? Still haven't found a clog yet. Rechecked vent pipe with waterhose and ran water through clean out. I did not see any back flow. Fustrating!!!!

These are two completely different things:

1. Water dripping out of your water supply in not related to you doing laundry. It is related to toilet installation and the problem can be either: dripping angle stop valve, leaking water supply line or leaking from the tank-to-bowl connection. There is also a remote possibility that your fill line inside that tank is not attached properly, water is splashing onto the lid and eventually drips out on the side of the tank.
You have to locate where is the leak coming from. Clean the tank, bowl, angle stop and water supply. Also clean the floor. Put paper towels on the floor and observe it for few minutes. See where wetness appears.

2. Water backing up to your toilet is drainage related problem. Are you sure your septic is not full and in need of pumping out ? It surely appears that that's the case...

You could snake it with small snake but most likely you will have to use 5/8" or 3/4" snake. Blockage can be only few feet away or 30' away. I would suggest you remove the toilet and snake it through the closet ring. Operating large snake is dangerous and requires some basic knowledge.
