Hi all,This past weekend, when moving our trailer to a new storage facility, I noticed that there is a small three legged crack (kinda a Y shape) in the front corner of the small basin side of our acrylic kitchen sink. It goes all the way through the sink material, so will be a leak if not repaired. I'm not sure if it was a crack due to cold weather over the winter, or if we damaged it somehow. This photo appears to shows the type of sink we have:http://www.rvandvansurplus.com/eshop/products/bone-sink.jpgA few questions on how to proceed:1) Am I correct in assuming it would be a waste of my time to try to get a warranty repair on something like this, given it's likely it was caused by something we did when using the sink, or during travel (we keep the sink strainers and soap dispenser in the sink, maybe a poor idea).2) Is there any type of waterproof tape (Eternabond maybe?) that we could apply to both sides of the sink over the crack to repair the sink for the time being?3) Is there a typical RV (read lightweight) sink that would be an upgrade from the very thin one the trailer came with that we could install at the end of the season?Thanks for the help!

I can't imagine it cracking on it's own. You might have accidently hit it and not even known it until you saw the crack later. If you're planning on replacing it anyway, and just want it to be functional for the time being, use some two part epoxy to patch it.

It could be a stress crack depending on how it is fastened down to the counter. You may want to try loosening the mounting hardware slightly if it has any. If the crack is getting longer drill a small hole at the very end of the crack and that will distribute the stress in all directions and effectively reducing the stress. That works for steel bridge beams. Then apply some type of epoxy to seal the crack.

I would use either a two part acrylic resin in white that you can add a color/dye to match your sink. Even stronger would be JB weld and paint the repair with porcelain appliance paint to match. Drill the crack at each end like mentioned.

here in ohio ours cracked, took it to a mom/pop cabinet shop, they ordered a repair kit of the same color , you can,t see the repair that was made . its gone..

Drill a 1/16 inch hole just beyond the end of each crack then fill the hole with epoxy. The hole will keep the crack from spreading.

You could use Eternabond tape on the underside for a temporary fix so it won't leak until you decide to replace or repair as noted in previous posts.

If it's a Y shape , something was drop. Acrylic are easy to repair.

Just because its been mentioned on this thread. Please do not use rvandvansurplus.com for any order. Check BBB or ripoff report if you don't believe me.

They wont issue a refund or send the parts and the ever elusive Bob will never return calls or answer the phone. Its a scam and they operate like 6 different websites. Check BBB or ripoff report if you don't believe me. The company is actually RV Marketing inc and its either the worst run business in America or a total scam. I believe it is a scam.

Thank you for the warning. I just found that picture from a google search to illustrate my sink style, but I'll make sure to avoid them.
