tires, batteries and now sewer lines
« on: July 14, 2013, 04:30:11 AM »
Hi All, driving from san bernadino to van nuys ca. to get nearer to work, on the I-210 fwy, an 18 wheeler which just pulled in front of me, blew at least two of the right back tires, at 70mph I could hear it in the bus with radio and air going, I saw the whole occurance shrapnel, pieces flying, and an entire carcass of one tire, in one piece, flying at me, fortunately went under bus, felt it hit the tires, and saw the jeep jump twice in the rear camera. Of course all of this in just seconds. I pulled over as soon as safe, and saw a big ruccuss behind me. jeep looked ok and didnt hear or see anything on the bus. When I arrived at the RV park, no brakes on the jeep, $1200 later jeep is repaired, I began to look closer at the MCI, saw some dripping underneath, upon very close inspection I discovered the black water sleeve and valve unit had been snapped off and was holding by a thin piece of glue. When I went to inspect it closer, it came right off, and the hole is rough on the plastic, holding tank. Has anyone repaired the drain hole, are they fixable? the female receptical seemed to have been glued on to the tank, and the 3" black hard sewer line to the valve that screwed into it are all glued together, I'll take a pic tommorrow, I put an Oakey temporary plug in the hole, thanks, lvmci...

Sorry to hear about this. Expensive accident. Wish the trucking company could pay for it. Anyway, are you absolutely sure the female fitting is glued into the tank? It might be spun weld but usually a threaded fitting is spun weld into the tank and you can unthread your pipe from that. Unless you're saying the fitting is broken which is annoying cause that will be harder to fix. Any pics?

  Sorry about your luck, that sucks..I hope the tank was mostly empty at the time, as, even though it wasn't your fault and if the tank was full, Calif. would have declared the spill as a major environmental disaster with mega fines. How about a threaded flanged outlet, inserted from top of tank and installing nut and gasket to seal and go from there? (after cleaning up and smoothing surface of bottom side of tank so gasket will seal properly). If outlet is too close to corner, is it practical to shift tank out a little for clearance?

Buy the plastic welder from H/F for 50 bucks with the correct rod material for the type plastic and weld the sucker it's a fairly good little welder for the money the 14 dollar one is junk

Hi Chessie, good suggestion, I wil pursue that idea, here's my idea to fully empty the black tank before leaving the park, the lip of the flexible coupler may be enough to seal the drain hole to wash out the tank,  lvmci...

After seeing the pictures-it looks like you could have a new fitting spin welded back into place. I would suggest you call at Ronco-plastics in Irvine and send those pictures to see if they are willing to spin weld a new fitting in. The web site is www.ronco-plastics.com  Good Luck, TomC

Spin,fusion and rod welding are about the same with plastics it's all done with heat spin welding is heat caused by the spinning of the fitting then if fuses together I doubt a spin weld would hold on a tank that old the chemical make up has changed over the years
