I have two back to back toilets. One flushes; one dont. The one that flushes bubbles into one that don't during flush.When I pull toilets both have standing water in drain lines I think because floating slab floor has sunk taking drain line down with it. Both sinks drain fine. One solution is excavate concrete floor in building and replace drain lines for $25,000. I was wondering if a new power assisted toilet might blow water and air through drain line and solve problem for $285?

THe flushmaster ads say they in effect create a drain flow that goes 20 feet farther than mere gravity /siphon toilet?

Any help greatly appreciated

there is no way the "slab could sink" enough for those lines to fill with water, unless you have a very unique piping installation. There is some other cause and you need a good plumber to cure it. IT may be something as simple as snaking the line, or, if you have a septic system, as serious as a deteriorated seepage field.

not sure why you say that given that code calls for 1/4 inch decline per foot of drain line. THe floor has sunk 4" so could have leveled out drain line. I did snake it out but it didn't help, and I have no septic.

Dropped floor seems like only possibility-right?

seems like you may headed for the $$$$$ repair anyway

? foundation issues ?

The power flushing toilets won't help.

If the slab sank 4" and the pipe was originally at ¼"/foot, the pipe would be basically level and any debris stuck on the bottom of the pipe could create a dam, holding back the water that you see. A level pipe will still drain, but solids would have a harder time getting carried downstream. Was a proper sized snake used, to try and clear the drain pipe? Has a camera been sent through the pipe for an inspection? If the pipe problem is affecting the toilet, why only one of them? If the pipe is the problem, can it be rerouted instead of replaced?

UNLESS the system dropped so far that the vent connection was under water, and for most installations that would be about 20", as long as the vent is open the toilet will flush. What happens AFTER the sewage gets into the pipe is another matter.

no foundation issues. THe slab floor floats but the foundation does not.

please tell why you think power flushing toilet bowl will not help. Manufactures advertise that they will push waste down line 20 feet farther!!

Was a proper sized snake used, to try and clear the drain pipe?
******yes a couple of times I think

Has a camera been sent through the pipe for an inspection?

******yes but it did give a clear answer about pipe decline


If the pipe problem is affecting the toilet, why only one of them?

******it seems one toilet is higher or its drain pipe is higher. THe good toilet drain makes an immediate right angle turn while the bad one goes down several feet


If the pipe is the problem, can it be rerouted instead of replaced?


******* no both pipes are under cement and go straight to street

thanks

Manufacturers also tell you that you can get 45 mpg with their cars.

If the bad one goes "down several feet", the that is the problem. THe end of it MAY be "under water" creating a double trap sitation which means the toilet will NEVER work properly, if at all.

yes, it seems the beginning of the horizontal drain line flows backwards toward the toilet, but it seems to me a power flush toilet may push everything through! What do you think!1
