New to the Forum and to RVing. We just bought our first TT, a 2000 Springdale Lite 25 with a number of problem,i have new tires and new electric brakes and bearing, so here's the first ? for you guys, Both the black & gray tanks a leaking where the pipes exit the tanks and at the valves. I know replacement valves are no problem . Previous owner/s have tried putting sealers around the pipes at the tanks, but the still are leaking. I know i will need to remove all that crap they have put on there before i try my fix. Any one tried Plastic Mend For ABS Holding Tanks, pretty pricey on Amazon at $40, but if it works, worth it . Any input welcomed.
