The main toilet in the house seems to have an awful lot of "give" to it. When you sit down, the toilet moves. The bolts connecting the toilet to the floor seem loose. We've tried to tighten them, to no avail. Any suggestions?

Get a package of wooden shims, and insert them in the front of the toilet. Gently tighten the bolts a bit, then see how it responds.

Thank you. We will try that and let you know.

You Need To Reset The Toilet, Go To Lowe's Buy A Wax Gasket And Johnni Bolts, And Also Pick Up A Buckett Of Plaster Of Paris--- Disconect The Toilet And Clean Up The Floor, Install New Bolts, And Wax Gasket, Then Mix Plaster And Put It All Around The Flange On The Floor (work Quick It Will Get Hard Fast) Install Toilet Tighting Bolts Connect Water, Then Wipe Up Excess Plaster With Wet Sponge. P.s. Do Not Overtighten Bolts.
