You dont. A tub drain is too small for a toilet drain. You need to hire a professional to find a main line 3" or bigger to tie into for a toilet drain.

No, a tub drain is too small for toilet plumbing. Toilet drains needs at least a 3" drain line and vented.


The clog is below the point where the toilet and the tub join the drain.


Yes as long as the drain has a trap and is vented


The tub and toilet connect to the same drain. There is not enough venting or how it is routed causes the tub to pull on the toilet to get venting causing a suction that lowers the water level or may cause it to flush.



The tub and toilet connect to the same drain at some point. The main drain was plugged but the connection between the toilet and tub was still open. Water seeks it's own level. When the water came up in the toilet, the tub was lower so some of it went there.


The drain is plugged between the tub and the sewer or septic or in the case of the septic system, the tank may be full. The toilet had to go somewhere and the tub was available.


It's not the toilet, there's a blockage in the pipes some where after the drain pipe from the toilet joins up with the drain pipe from the tub.You're going to need to have the pipe snaked.


There may not be a trap in the line on the toilet drain. The stool acts as the trap keeping sewer gas from coming up. If there is access to the drain from below then a trap could be installed.


The toilet itself is plugged or the pipe from the toilet to the drain is plugged. It may be that the tub and sink have their own drain pipe that may connect to the main away from the toilet drain. Plunge the toilet or sometimes if you fill a 5 gallon bucket with water and pour it into the toilet as fast as it will take it, that will flush out the line. It is a greater amount of water all at once an forces out what the clog is.


A tub drain vents through the overflow.


== == == == == == If you have an open septic tank or broken sewage pipe anything that crawls can get into your toilet or bath tub or sinks. You can buy a special trap device to keep all creepy crawlers out of your sewage pipes. The device lets the water out but it won't let the critters in. Keep a tub screen on the drain in your tub to reduce spiders from coming into your bath tub.I have seen a snake come out of my own toilet. Spiders come up out of the bath tub drain all of the time. I live in the woods. You can expect the unexpected when you live in a forest.


The drain from the toilet to the main or the main itself is partially clogged or collapsed. There is probably enough room for the sink to drain but the washer puts out so much water all at once it can't get through and backs up into the tub and toilet.



Supply lines- Hot and cold water for each sink, bathtub, Jacuzzi tub, and shower. Cold water for each toilet. Drain lines- one for each sink, bathtub, Jacuzzi tub, shower, and toilet.


Once the old tub gets into the drain it is impossible to remove.........


Usually. Going through the overflow drain gets you straight into the drain without having to make the sharp bend in the tub drain. There could be a trap that comes apart in the drain underneath if it is accessible.


15 inches from outside edge of tub to center of toilet flange.


Connection of the washer drain hose to the tub drain is very important. This will help prevent leaks for example.


You can't, the shower drain fitting is larger. You must fit a conventional tub overflow and drain



Usually toilet flange is glued down onto plastic drain pipe. There is a toilet flange that can be glued inside of plastic drain pipe also.


The toilet will gurgle as it sucks air through out the toilet trap. You may even hear it suck air through a nearby sink or the tub. Sometimes it may just drain slow or weak.


Your drain line from the toilet is likely plugged. as far as the tub filling up, the tub probably drains into the same large line so it is also plugged, but the sink drain line comes into the main drain downstream from the plug, so it is still working ok. You need to call roto-rooter or similar and have the main drain snaked out. To do it yourself as much as practical, you can buy or rent a plumber


The piece in the drain is screwed into the drain under the tub It is usually corroded and is not going to unscrew. You can use a sawsall or jig saw to cut the drain in 3 or 4 places around the opening and peel the piece out. You can also disconnect the drain under the tub and just leave it on the tub. There should be access to the back side of the tub. Usually a panel or door in the back of a closet that is in the room beside the bath. If there is no access, you will need to make one so that you can connect the drain to the new tub.
