My 3 1/2 year old Insinkerator insta-hot water dispenser (model H770)
sprang a leak in the plastic case. I can't even see the crack but a
soap water bubble test while pressurizing the tank shows it is there.
It seems to be near or along a 'rib' of the plastic tank.

Can anyone suggest an easily available high temp, waterproof glue or
patch material to try a repair? It's hard plastic and obviously stays
quite hot all the time with 190+ degree water in it.

I see the newer models have a stainless steel tank. The company says it
is to stay competitive. I wonder if that's the real reason.

Thanks for any repair suggestions before having to purchase a new one.

I'd say you'd be miles ahead replacing it.

If one crack developed over time, who's to say another one won't occur a
couple of months after you spend all sorts of time patching the present one.

I just replaced our kithen sink's Insinkerator Insta-Hot when I noticed
a wet spot on the cabinet floor beneath it. That bugger had served us
faithfully for at least 21 years.

I couldn't resist opening the old one up before I chucked it to see how
badly shot it was. It had a copper tank in it, so they must have
switched to plastic at some time after ours was made and then went over
to stainless steel, maybe because of too many problems with the plastic
ones.
