Cracked leaking Blanco Silgranite Sink

Our Blanco Silgranite sink has a long crack in it that leaks slightly.

Blanco has offered to replace it under warranty. Trouble is, the model is discontinued. Custom countertop was cut to allow for the sink. I think ití was just a design element to allow for the two corner sponge holders. Blanco has said any replacement will likely need to be installed as a drop in. Could another undermount work?

Iíd really like to keep an undermount.

Whatís a good temporary repair? Silicon? Form the top? The bottom?

Whether or not another undermount will work depends totally on the sink. Either it will fit or it won't.

For a temporary repair I would sand the underside/outside of the crack area. Wipe down with a solvent to remove any soap, oils and dust. Then smear on a strip of roofing rubberized roof patch or one of the wonder leak stopper.

Is it simply a matter of fitting in the opening and the faucet holes? Mine doesnít even seem to use any clips. It appears to be supported by 4 pieces of 1Ēx 1.5Ē strapping.

You can't use clips on a stone countertop.
Strapping or similar and silicone between the sink and the countertop.

JB Weld would be a good choice to "fix it". I've used that stuff on a cracked transfer case on an old Ford Explorer. Sold it 3 years after the repair, never a drop from the repair !!

Thanks for the advice. Leak is stopped. Looks like Blanco is going to send me a replacement, different model.

Theyíre sending a template first to see if it will fit. Probably means dropping in an over mount, although I fear the rounded edge at the top will prevent this. Donít really want to cut the countertop to fit a rectangular model in.

Lesson for everyone here....although I think sinks rarely crack......getting any other shape rather than the standard rectangle could lead to issues if you ever need to replace it. Fancy sink design means customer cut counter top. And that means youíre screwed if a replacement is needed.

The model I need is a Somerset 210....in case anyone knows of any dealers or stores that might carry discontinued models. Canít find any here in Canada.
