Sounds like the wax seal at the base of the toilet, where it bolts to the floor, is leaking! If you are handy with tools, here's what to do: go to Home Depot or Lowes. or the local neighborhood hardware store, and buy the wax ring for the seal to the floor! On the base of the toilet tank should be a water shut-off valve! If not, go down cellar to where the main water supply line is, and shut it off! Go back up to bathroom, flush the toilet. pry off the bolt caps, remove the nuts, lift up the toilet from the bolts, pry off the old wax seal, clean the area well, lay in the new wax seal, reinstall the toilet, install the nuts, don't tighten them so much that you crack the toilet base, install the nut covers, connect everything up, turn on the water, and you should be good to GO! and, you'll really impress the MIL by your prowess! Some applications of Drain cleaner should fix the water drain back-ups! Drano, or some other hi-test cleaner, like Liquid Plumber should do it! The only other reason for drain back-ups is: you are overloading yer septic tank and system, what with the dish-washer, and many loads of wash! The drain fields are probably plugged up, which can cause many problems, especially if your septic tank and system isn't big enough to handle all of the water you are putting into it! Try this: do the dishes by hand for a while, and take some or all of the laundry to a laundry place where they have the machines, or cut down on the number of days you do the laundry, so you can see if that helps the situation! Another thing--don't flush the toilet every time somebody tinkles in it! (That is what some of the rural folks have or had to do with being on a septic system! I know, its not how you were brought up, but its necessary at times when on septic systems!) Do this, until you decide if that might be helping the problem, too! You might need a bigger system installed, like larger tank-s! Get the plumber to do a dye test on the tank-s and fields and laterals. Good luck: rustyj

Our house had been re-done right before we bought it and every toilet replaced so they are all brand new, however we hate them. They are all eljer brand which I thought was a decent brand. They clog very often with no reason to and they are dual flush but they never flush anything with the light flush, you have to keep the handle held down till it finally puts enough water in to flush which is frustrating. The flush levers have broken on 2 of them already which we had to replace. And they are the low ones with the round seat not elongated I absolutely hate round seats. It is a shame to have to replace such new toilets but we are definitely shopping for at least 2 of them. Looking at the Eljer website shows that the ones in our house are quite expensive ones too. I have found those molded with the curves toilet seats available in replacement seats so you may want to check around and just replace your seat with one of those.

"toilet water porting problem" Not a term used in the plumbing trade. I suspect that this is not a serious post. But if it is, one test is to quickly pour a bucket a bucket of clean water into the toilet bowl. Watch how it flushes and how the remaining water looks after that.

A proper complete flush requires approximately 2-1/4 to 2-1/2 gal to flood the trapway and begin the flushing action. Years ago water closet tanks discharged 5gal, then 3.5gal which was actually an excessive amount to cause the flush action. With the advent of water saver regulations they designed the bowl so that it would retain approx 1 to 1.5 gal as the trap seal, then they determined the minimum amount of additional water it would take to cause the flush, which works out to be 1.6gal. If you lower the standing water in the bowl, not only does that risk the trap not sealing correctly, it also starves the bowl for water during the next flush resulting in an incomplete flush, as is described by Plumbman after he removed the trap primer line. Take my word for it, the level of water in the bowl and the level in the tank are both critical if you expect the water closet to flush as it is intended to do.
