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. Since my connections were already streched out, I did the following: 1. I shaved the ribs off the spin on fittings and placed a hose clamp moderately tight around the fitting. 2. Applied marine grade silicone sealant to the male and female threads 3. Turned down the elbow and at the same time increased slightly the pressure on the hose clamp. 4. Turned the elbow down hand tight + a quarter turn with full preassure on the hose clamp. 5. Let sit 24 hrs prior to test 6. Test at 1.5 psi (water coming out the vent at a 4' head is approx. 1.5 psi),24 hrs 7. No leaks |

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. :) -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://www.seaworthy.com/html/get_ri...oat_odors.html |

a failure. Must be the luck of the draw :) Doug s/v Callista "Marc" wrote in message ... Ronco Plastics no longer recommends teflon tape for their tank connections.

... A wise old industrial plumber gave me that particular advice. This same wise plumber also should have told to to stop one quarter turn before breaking... ;-) And to add to the use of teflon tape: I have regularly used it at pressures up to 80 psi without any sign of leakage. Meindert |

This something that's most likely to show up immediately while replacing a tank and/or hoses..which assumes that you've bought fittings to do the job. To pressure test the tank after you've connected all the hoses, fill it full to overflowing with water, then block the vent and pump the toilet in the dry mode till you feel some real backpressure (if it's been more than a year since you've replaced the joker valve in the toilet, do that first). Put a quart of water in the bowl to act as an "air break," then go away for a couple of hours. If there's no moisture around the fittings, you're good to go...if there is any, replacing the leaking fitting will most likely solve the problem. Almost any yard or boat store sells thread to barb tank fittings...you can do it yourself. Avoid 1.5" PVC fittings, because for some arcane reason known only to the plumbing industry, nominal 1.5" thread x 1.5" barb fittings are actualy 1.5" thread x 1 5/8" barb..which makes it d'd near impossible to get a hose onto it. Marelon and nylon thread-barb fittngs are actual 1.5" barbed. All of the above assumes a plastic tank with threaded ports. If a welded or caulked fitting in a metal or fiberglass tank is leaking, that's a repair job. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://www.seaworthy.com/html/get_ri...oat_odors.html |
