WW fresh tanks

My WW has (2) 50 gal fresh tanks. They are ABS and joined by 1 1/2 (?) hard pipe. I have a leak caused by the 2 tanks being joined by the hard pipe that I fixed with Plasti-mend. The flexing between the 2 tanks killed that fix and it's leaking again. I would like to join both tanks with some kind of flexible tubing (?) that is fresh water safe. Any suggestions on what to use (tubing, hardware, etc) and possibly where to find the parts?
  • I'd go to Home Depot and get some of the clear tubing with the reinforcing mesh in it. I think they make it up to 1.5". When running it from one tank to another, make a loop or coil in it to absorb the RV frame flexing and tanks moving around. Fasten the loop to the bottom of the RV with some plumbers tape. Check the loop for water when winterizing.
