Ronco Plastics no longer recommends teflon tape for their tank
connections. During my tank installation, I performed a 1.5psi, 3hr
test and the connections failed. I spoke to Ritch at Ronco and he
conceded that teflon tape is not their choice any more. He recommended
a butyl rubber sealant.

Weeeellll...the "sanitation" hose in their 2000 catalog was corrugated
hose that needed cuffs. So while Ronco builds excellent tanks--not just
for marine and RV use, but many industries--they're not the best source
for advice about marine installation standards....which call for no
sealant, only Teflon tape. I suspect the real problem was an
out-of-round thread-barb male fitting...they're not exactly made to NASA
tolenrances, so it not that not uncommon. But you've done it...so just
inspect at least annually for signs that the sealant is failing and
meanwhile, relax and enjoy your boat.

Btw...standards also call for two hose clamps, with screws on opposite
sides of the hose on all sanitation system connections...to prevent
leaks and as a failsafe. So if you used only one, you have one more
small job to do to finish it...and THEN you can relax and enjoy your
boat.
