Have you thought about upgrading to the larger bottle GWW906? These use the same mounting bracket as the earlier GWW916 bottle which is what it sounds like you have.

Surely far easier than fixing what you have with the added benefit of larger capacity.

I used this stuff to fix a hole in a plastic master cylinder reservoir and it works amazing.

The permatex is like a JB weld for Plastic, just make sure you clean the surface first.

that permatex sounds pretty good. just need to see if it works on poly.

I've used Mr Sticky's Poly-Bonder to repair a drain fitting on my rv water tank. worked great.

The best way to repair it is as said before. Use a soldering iron or plastic welder and add poly to the outside of the bottle.

You need a plastic welder. A soldering iron can be made to work in a pinch, but it's easier and more fun to use the proper tool.

There are lots of different HOW-TO videos on youtube. Just google Plastic Welding.

 

Rick, the statement on the directions for the 6000 stuff says it won't work on polystyrene, polyethylene, etc., and the model plane glue I tried sure didn't stick either. As noted above, the bottle is probably one of the poly plastics. So, I'm not keen to pour a bunch in there, have it harden but not adhere, and then be unable to get it back out (as I have the model plane glue by breaking it up and grabbing it through the neck.) TA2DMAC, what add'l can you tell me about the RV stuff? will it adhere to poly plastic? Soldering iron.....buttering bread.....I can feel that turning into a bigger disaster....

Go to an RV store and pick up a plastic tank sealer/repair kit. They use it on the the septics.

Or if your creative,get a  cut a piece of an oil container or plastic zip ties, prefereably same color and a soldering iron.

Use the iron to melt the bottle where the leak is.

Push the plastic into the leaking point.

Then spread the plastic over like you were buttering a peice of bread.

Check to make sure it's sealed.

 Then overlap it with the zip or oil container plastic like a patch to strengthen it.

Oil bottles use the same kind of plastic.

Third option replace it with a mason jar and a strap.

 

Seal all will work, it seals gasoline, oil , and its clear. Comes in a yellow tube or spray can. I guarantee it. BOBB

I'm positive the E 6000 adhesive will work. It's actually 'self leveling', so if the holes are in the bottom of the washer bottle, coating the entire bottom with a thin layer will work perfectly. It's called 'potting'. It dries so clear that it's virtually impossible to see. Just make sure it's clean and dry where you apply it.                         Mini Estate

P.S. Sorry George, I thought this glue was the mother of all fix all's. Apparently it doesn't work on the poly. Maybe the guy on TV that sprays the srceens for boat decks can help? HA!

I think the plastic bottles are all made of polyethylene.  That means virtually nothing is going to stick well.

If the pin holes are on the back side and not seen, I suggest taking strips cut from an old milk jug and using a new (clean) soldering iron tip to melt the milk jug plastic into the pin holes.

Aloha George,

I would suggest E 6000. ACE Hardware should carry it. The only problem might be accessing the area where you need the glue to go, as it comes in a tube. It's waterproof. It comes out clear, it dries clear. Follow the directions. It needs to cure for a day or two. It's pretty advanced adhesive. I doubt if most people have even heard of it. The tube is grey with a bold E 6000 in white letters. Hope this helps.     Mini Estate

OK, need some of the collective wisdom here. I have an OE washer bottle, small D-shape, not replaceable with new. It has what seem to be pinhole leaks in both back corners. I've tried dripping model plane cement into the corners, but it's hit or miss, mostly miss. What I'd like to find is a substance liquid enough that I could pour it in to create a new "bottom" for the bottle, about 1/4" deep, that would stay liquid long enough to level itself, but then bond to the nalgene-like plastic to eliminate the pesky leaks. Should be clear or white. ACE hdwe has a startlingly large array of adhesives, but nothing seemed just right.

Any ideas? Yes, I know I could make a bladder with a bag, but that's bodgy-looking around the cap and temporary.
