My mothers toilet will not flush, its like theres no suction, when flushed the water in the bowl goes down very slowly but not all the way down to the hole and when it does its very slow weak suction. I snaked it and still nothing. Whats wrong?

Look inside the tank under the lid, it sounds like the flapper that lets the water into the bowl is getting hung up on something when you flush. It could be the flushing lever. This would cause the flapper to stay open letting water to just pour into the open sewer line. It should be a simple fix. Just see what is binding the flapper & make an adjustment.

You have a partial clog, as if someone tried to flush paper towels or something that shouldn't have gone in the drain.

Try plunging, first, then a toilet snake, or you may have to get a pro to pull the toilet off the floor and run a larger snake if it's further down...

you have a blockage maybe outside in your shores

Sorry for problem with new toilet.
You say water is leaking out of the bowl?

Toilets have 2 parts:
1) Tank: where water is stored for the flush and is sealed with a flapper.
2) Bowl: where water flushes down.

a) If tank is leaking water, then flapper is suspect. Replace flapper and see if that works.
Lift up flapper and run finger around rim to see if there is a rough spot that would indicate flush valve is defective, and needs replacement.
See typical flush valve

b) If bowl is leaking, that is very unusual and would indicate a crack in the porcelain.

If installer sold you the toilet, it is his responsibility to make good on product.

Sounds like you have a clogged drainline or vent-stack. Fill a large bucket with about three gallons of water and dump it quickly into the bowl. If the drainline/vent is clear, the toilet will "flush" like a gravity toilet and the water will drain from the bowl almost as fast as you can pour it in.

If the water level in the bowl slowly rises (as if it's about to overflow) and then slowly drains, you have a clog somewhere.

All toilets, regardless of their flushing mechanism, require a clear, unoibstructed drain/waste/vent system to extract waste.

If the toilet "flushes" with the bucket of water, you may want to call Flushmate tech support (the number is on top of the tank) or check out the installation and troubleshooting videos at howto.flushmate.com.

Hope this helps.

Check to be sure small tube is flowing inside the ovefow tube. This is the water that flushes the rim holes, and refills the bowl. If you don't have flow clean or replace the float valve.

The small black tube that goes into the overflow is used to fill the bowl after flushing. Would check to make sure that water is coming out of that tube at full force or if its coming out at all.

Sounds like your toilet is not vented properly. Possilbly something caught in the trap is causing it to syphon

it sounds like it is not flushing completely at first and then releases and the suction is pulling water out of the bowl. Could be a venting issue or a clog issue that is hindering the proper flushing of the toilet.

Problem solved.  Reason was a totally blocked waste line that resulted in toilet malfunction.  Toilet functions normally now with removal of blockage.
