I have a small hole in my double skinned flexible water tank. It looks like the inner lining is polythene can this be patched?
Thanks

Perhaps, but I've never had much success in mending plastic.
I've just had the same problem and found that the recomended adhesive was going to cost 2/3rds the cost of a new liner.
Not worth the aggro for me.
If it's a Plastimo tank, the liners are available at considerable saving, although the chandlers will try to flog you the complete kit.

I had the same problem last year in Gouvia marina. The inner membrane is coated with an anti-fungal/anti-smell lining and I found it impossible to repair successfully. You may have to bite the bullet and buy a new tank, especially if it was made to measure for a certain space - as mine was!

i did this mending 3 years ago just plastic welding with this cheep el gun with plastic sticks. Did it from the inside (you can open a big lid i presume)
works well so far - but it was a small hole

I did mine about 1 1/2 months ago still seems sound.
I used some small patches cut out from the black floor repair rubbery stuff (easy!) and polythene cement from the dinghy repair kit. I used wet and dry paper to clean around the holes (5 holes found!) and a roller to get the patches as bubble free as possible.
I am struggling to find a membrane; This is meant to be a temporary repair, though if it does not leak I will treat it as some other temporary fixes and rename it, fixed.
Mine split in folds due to bad positioning after I changed all the water pipes and cleaned the tank out of the boat. The membrane has gone very stiff at one end after being left dry for years at lay up, I turned the membrane over so now the soft half is taking all the work of expanding and contracting with water.
This is probably an illegal fix in PBO terms, but it seems to be working out so far.
