I bought the Aquawash Ambient Bidet Seat, Model 5900A05G in August.  We loved it! Bought the AquaWash Bidet Seat in August.  We loved it!! Simple to install, worked great until...it started leaking. A slow leak from the connection point of the hose to the seat.  I've tried Teflon tape, plumbers putty, tightening more, tightening less, and it just keeps leaking.  Any suggestions before I give up and buy a different brand?
