Talking freshwater tank hole.......material and plastic weld kits...

i just picked up a 75 tradewind the other day....pre-purchase inspection revealed a rusted steel support area forward of the axles....ok....this saved me 500.00 of the asking price....

in the process of grinding some of the steel angle off and cutting out the 1 inch plywood (after removing 3 alum...skins) i put a cut into the freshwater tank...this cut was made with a jig saw and is about 2 inches long on the bottom of the tank....

i want to patch this cut with a plastic weld kit....most kits say they will work with any kind of plastic except for "polypropelyne" (sp?)...one of the kits from autozone will do the polypropelyne plastic but it needs to be warmed up first...

in the future what plastic weld kits have you guys had luck with...best / worst...

all said and done ....what is the plastic that makes up the fresh water tank on a 75 tradewind...other then this rusted support area...trailer is in great condition...i would like to buy a rock guard but i cant seem to locate a supplier online....i live in central florida if you know anyone local selling...

thanks for your time and effort.....

Rock guard

Hi I can not help you out on the type of plastic used for your tank. But you will more than likely find a rock guard at Inland RV http://www.inlandrv.com/

The tanks (fresh water and holding variety) on the 70's trailers are made of polyethylene. If kept out of sunlight (UV light) it will last indefinately. It can be "welded" with a plastic welder (specialized heat gun) and polyethylene rod. Problem is doing in place. If you can remove the tank and position it so that the damage is in a horizontal position, it's much easier to do. I've used a Weller soldering iron and powdered polyethylene to fill small holes or cracks. To prevent the cut from cracking further, drill a small hole at each end of the cut before welding. Use a hair dryer to be sure all the moisture is gone before welding. Work slowly and don't overheat the plastic or you'll make a bigger hole. DON'T BREATH THE FUMES! Darol

Talking thanks

i am going to work on this tank this afternoon or tomorrow...tank is out of frame and can be sit up and fill tested....we are going to weld new supports and replace ply with 3/4 inch marine .....

what suprised me was the tank was just sitting on the ply (which was rotted) no bands or other supports at all...i expected it to be banded into the frame supports someway and the ply would just be an easy access point...nope.....pulled open the ply made a note of connection (sensor) positions and down came the tank....

Lee,

I regularly use a plastic welder from Harbor Freight. They made a knock-off of a Seelye unit that uses air flow over a ceramic heating element. With about 10 minutes practice on some scrap plastic, you can do a very good job of permanently repairing your tank. Just be certain that you use the proper welding rod of the same material as your tank. Good Luck!
