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.

Re: Stus-List Water Tank Woes [again] - Welding Question

[bwhitmore via CnC-List]

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.

Water Tank Woes [again] - Welding Question 

My water tank is leaking again. I want to attempt a weld to repair it.
 
It is a Kracor polypropylene tank, but the labeling details have faded over 
time, and no longer legible.  I don’t know what kind of polypropylene was used 
to construct the tank.

 So, the question is, do I use hi-density OR
lo-density polypropylene?  Or, does it matter?
 
Thanks!

Give Kracor a call.   When I had a problem with one of my tanks they were very 
helpful.   The tank had a crack at the threads and  I was able to repair it 
using their instructions

If the fitting was screwed in too tight, it might have put a small crack in

Re: Stus-List Water Tank Woes

[Danny Haughey via CnC-List]

Kelly,Have you tried replacing the fitting?If it's a poly fitting it could have 
gotten damge to the threads or mis-shaped somehow...
Worth a shot I think. 
Use some good Teflon tape and maybe some kind of pipe sealer.   I used to use a 
product called 'grip' when I was worried about leaks.  It's messy though and is 
hard to break the joint later.   Also,  you don't want to use too much Teflon 
Tape on the joint.  Just a few wraps.

Re: Stus-List Water Tank Woes

[Frederick G Street via CnC-List]

Dennis — have you forgotten about the boat I worked on several years back that 
was struck by lightning?  It was a really hot day, and the second day of a 
charter; the boat got struck, and had to be towed into the marina.  I went 
aboard the next morning; it was about 100F below, and reeked to high heaven.  
It turns out the boat had a flexible holding tank up under the v-berth; the 
lightning came down the mast and side-flashed through the half-full holding 
tank, causing it to explode.  The resulting “liquid” cooked below in the hot 
sun for a day and a half.  It took them quite a while to get rid of that smell.

Okay, so maybe an extreme example…   :^)

Re: Stus-List Water Tank Woes

[svpegasus38]

Let me be the first to post about a failed flex\bladder tank. Pegasus had 
2, 1 for black water (leaked), the other was a square tank under the v berth. 
Could only put 10 gallons in a 40 gallon tank. Rest was air. Replaced both with 
plastic much happier.

Harry, Kracor is a brand and they are molded LLDPE plastic.  Welded tanks are 
made differently and they are either LDPE or HDPE.  Molded tanks are generally 
higher quality than welded tanks.

Stus-List Water Tank Woes

elbow fitting exits the tank .  I've wrapped the threads with Teflon tape [both

fix it. 
The tank is a Kracor brand, and the tank's walls and bottom appear to be quite

fitting is screwed into it.

Re: Stus-List Water Tank Woes - 30-II

[Stevan Plavsa via CnC-List]

I had a fitting on my tank plastic welded, it's good as new.
Since you're taking the tank out anyway it's a good time to clean it ..
filled mine with water and bleach and let it stand that way overnight then
rinsed and repeated. My tank was really smelly, the PO left it with
plumbing anti-freeze inside for a few years :/
After that I let it sit full of baking soda and crumpled newspapers over
the winter and the smell is gone.

Re: Stus-List Water Tank Woes - 30-II

[Ken Heaton via CnC-List]

I'm including a link to a video about a TAP Plastics product that works on
polyethylene tanks.  Note this product will only work if you use the flame
surface treatment shown in the video, starting at about 2:10.  Without
proper preparation through flame treatment it won't work.

https://www.youtube.com/watch?v=h-9yhanz5DE

You may also be able to take the tank out and have it plastic welded.  I
have no experience with that though.
