It is not simply high or low density?the tank was made from LLDPE and rods must
be the same material.

Hi Pete,
Plastic welding is the way to go. I tried various ways to repair tanks, but my
welded repairs (I fixed 3 tanks now by welding) have had no problems. Plastic
welding is rather easy to do. The key is getting good plastic welding rods.
I normally use a hot air welder, but if you are very careful, you can use make
due with a propane torch. Though I highly recommend borrowing or buying a
welder. Harbor Freight sells a reasonable welder for about $60, and since they
always have 20-25% off coupons, it would cost about $45.
Small leaks are easy to fix. If you have a more serious repair, like a long
crack due to poor structural support, then repair and split it with some 316
stainless mesh.
I purchased a package of 1/8" LDPE welding rods from Grainger. As I recall, it
was 50 rods for $15. I also purchased 316 mesh from Grainger.
I have details on my blog. Below is the link. Skip down to the section on
plastic welding.

I 100% with Paul's comments below.? By the way, it will likely take more
plastic welding rods than you think.? In a pinch I cut up some Tupperware type
lids that were labeled LDPE and they sufficed when I ran short.? That said, not
all LDPE is the same, and HDPE will definitely NOT work for welding LDPE.Hoping
you find this helpful,?Bruce?Sent from Samsung tablet.
