I have a small leak on a corner seam in my black water tank on my 5th wheel.
Is this something I can repair myself with JB Weld or a similar product?
Thank in advance for your help!!

ABS tanks can be easily, successfully, and inexpensively plastic welded. I've had several repaired by a professional. I see Harbor Freight offers a plastic welder, but I don't know if it is a worthwhile tool or how much skill is involved.

Black ABS can be repaired with a product called Plasti-Mend. If the damage is due to stress flexing on a corner consider adding some sheet ABS to stiffen the repair.

I used the HF plastic wielder with good success. I first melted the wire screening over the cleaned area to be repaired, then added repair plastic over it.

If the crack is on a bottom corner, odds are any type repair will be futile, due to the tank flexing when full and empty. But, it does not hurt to try. Make sure the area is CLEAN and DRY. Use sandpaper to rough up the ABS. Then apply the plastic glue material WITH a small piece of standard fiberglass screen material to strengthen the repair and prevent the tank from flexing. Is this a CRACK? If so, you will want to drill a small hole at the end of each end of the crack to prevent the crack from continuing. Doug

I'm a little confused on the type of plastic the tank is made of.
I contacted the manufacturer of my trailer and they said it was LLDPE. In my research it says LLDPE is white or yellowish in color. My tank is black in color. My guess is it is ABS....does that sound correct?
