Our old toilet would not fill up the bowl after flush. Had to pour water into bowl to keep water from exploding out when flushed. Housed out air pipe on roof. No help. Purchesed a new fast flush toiled and it is doing the same thing. Poured about 4 gallons of water down toilet 5 times. Flushed fine. Still low level in bowl and air exploads out when flushed.

Was there any delay between the flush and the explosion? Let me know. Tom

No, it is almost instant

What type of bowl do you have? A wash down or jet? A jet has a small hole in the bowl while a wash down has none and works on gravity.

. Poured about 4 gallons of water down toilet 5 times. Flushed fine.

And it exploded the sixth time? Back to you, Tom

Was down. Maybe exploaded is to strong. Water is blown out when I flush without pouring in extra water.

What I think is happening here is when you flush, The bulk of the waster goes down instead of into the bowl filling it up until it siphons out. I think the water from the tank is hitting the water in the trap,(see image) and bouncing back with force exploding out of the bowl.
OK! Now I've told you what I think's going on but I can't give you a repair for it. About the only thing I can suggest is to replace the wash down bowl with a Jet type bowl. Wash down bowls are supposed to fill the bowl with the bulk of the flush. The only thing that Comes to mine is that you got two faulty bowels in a row. And your thoughts? Tom

After reading other toilet probs. It seems like I have a partial block down the line. I live in a DW mobile home. The guest toilet,other toilet on other side of house works fine. The one in the master BR is the one. I cannot see anything with the toiled removed. The line runs across to about midhouse and joins up with all other drains then out to septic tank. All sinks work fine, tub in master bathroom drains slow. Never use it always use shower. I am going to pour draino down tub and washing machine drain. My wife now tells me the tub gurgals when washer is draining. Wish me luck.

Did not help. The back side of the house has settled about an inch or 2. Would this effect the toiled because it is not level. The main drain under the house is slanted down.

The master tub drains better.

This is why I asked you,"

And you answered,

it is almost instant

Unless you have a clog real close to the closet bend it seems it would be a short delay between the flush and the explosion. Make sense to you? Makes sense to me! Let me know what you find. Good luck, Tom
