Sealant

[T1 Terry]

Two suppliers come to mind, Nightingale Supplies in Northgate Qld, and http://www.abldistribution.com.au/p-802 ... esive.aspx but a google search for Simson70-03 will turn up quite a few more potential suppliers

I bought it a few years ago from the Winnebago online shop

They have incorrectly called it "Simpson" but it is in fact the Simson product you are looking for.

Can anyone advise a sealant to repair a small leak in a polyethylene water tank?

How about a piece of suitable plastic cut a bit bigger than the hole and use superglue (on a clean surface of course)

"tanks" here George---
I was thinking of Selleys KNEAD-IT polymer repair stuff. I got mine from Bunnings --however on reading the instructions they say not suitable for Teflon, Use Selleys Plastics Glue for Polyethylene or Polypropylene.

Hope this helps.
Keith.
p.s.: KNEAD-IT is great stuff to carry in the tool kit for almost anything that needs fixing.

George I'm assuming it's a tank on your motorhome?
On houseboats a product that is commonly used to make black & grey water tanks by 'cementing' in outlets & inlets is Ferropre.
It is a two pack product. Part A & B.
Made by Henkel Adhesives in West Hildelberg in Melbourne.
Fully approved by EPA to ensure no polllution of the Murray.
Follow directions & it'll outlast you.
It should be readily available at any good plumbing supplier or ask your local plumber.

Thanks Terry, better price than Sika to boot. I'll get some and give it a shot, shame I didn't ask before as I am near the end of using this stuff now.

Thanks to Dot, Keith and Bruce. It was an enquiry for a nephew and I am not privy to the details however I directed him to a Selleys product to consider.

George,

Poly tanks can be welded if the hole is not to big. I drilled my tanks for senders which turned out were rubbish so I needed to plug the holes. The holes were 3/8" to big for welding plus they were in place and to hard to get out. I wound up using 316 stainless bolts and nylock nuts with large stainless washer with a good dob of aquarium silicone. It depends on if you can get to the nuts inside of course.

You are going to have a problem getting an adhesive for your poly tank. Plastic welding is the better choice if possible. I ended up using the Simson sealant on my poly grey and black tanks but also used a mechanical method (bolted) to assist. This way the simson sealant is used to seal and the adhesion is via bolts. It has held tight with no leaks for about 6 years now. If you do use a type of sealer then you must prep and prime the tank. Simson do a primer for this purpose.
