No, if installed other way the fixed water jet would point in the wrong direction
I'm sorry I cannot answer your question because I have not experienced a leak. I would suggest you call the manufacturer.
Just remove the toilet seat and install this inbetween. uses the standard mounting holes in each individual toilet.
Exchange it. The unit is definitely not working the way it should be.
Mine leaked also.
I dont think so you have to order left hand side
If installed correctly, you should have good pressure. I installed in all my toilets (3) and no issues. Check if you have good flushing water and your tank fills like normal. If not, check valves and open valves all the way.
I have an elongated 1 piece toilet and the seat easily install over the unit.
everything is included
Yes, this will fit any toilet as long as there is a detachable seat.
