Hi frankielynn, The one I'm trying to fix now is a 300 gallon. I had 2 others that were 100 gallons, and had cracks at the bottom, which I couldn't fix. But that was about 5 years ago and I used a glue-type thing. So maybe this Waterweld will work better. I'll keep you posted. Hopefully, it can make it through the summer. Good luck on yours.

What is the sink made of? Does the faucet have a trim plate that covers the holes? You can get through just about anything with the correct bits. Hole saws are even available with diamond if needed, but carbide does just about everything short of hard stone.

Thanks for the help! I just spoke to Blanco Customer Service. There are four additional knockouts for accessories. However, it took half a day, lots of internet searching, a couple of phone calls, one to HD and one to Blanco to find this out. I wouldn't even have known to look for the additional knockouts if you GWebbers hadn't led me in that direction! When I kindly suggested to Blanco that they add this on to the description and make it clear to future potential customers that these knockouts are an option, well, she was let's say 'less than grateful'.."ma'am we have that information on our website". Well, perhaps not every customer wants to go back to the manufacturer's website to try and find that out (model numbers are different from what is stated on the HD site, and in fact she gave me the wrong model number at first...) Anyhow, now I know, I thought I was doing Blanco a service letting them know it was not that clear, and it could be helpful to add that to the HD description..." Ma'am that is HD's description" Oh well, you can lead them to water....

the time to drill a hole is measured in seconds. This assumes the drill bit is the right one. I think that 99% of men with drills will be proud of their tools and drill as fast as can be done, as long as it's safe. Not "too fast". The drill can turn slow, or slower, or faster. But thinking of a normal hole being drilled in a mere matter of seconds causes a problem. The problem is that this mindset does not slow down the process to include a low-dust result. Getting water to be present = lower dust. the time to drill a hole is measured in minutes, many minutes) if you go slow enough to ensure that water gets into the groove as it is being drilled. Dust is minimized when water is present at the point of contact where the drill bit meets the material being ground down by the drill bit. You might have to back out the drill and go back in. Wasted seconds, if you are thinking of doing it relatively fast. A total waste of effort if you think it's dumb to have to repeat the up and down operation again a mere second later, and again, and again. I guess the only way to get the guy to drill slow is to make him feel pride in reducing dust. This new pride takes time to develop. Lots of talk, beginning early in the day. Like shar-az said in another thread today, sometimes you have to say things more than once. the time to drill a hole is measured in seconds. This is nothing, or almost nothing, when you add up all the time it takes to get to the job site, get set up, measure things out right and do everything else right. So, it stands to reason that a worker holding the drill could adopt the attitude that he is going to do 20 or 30 passes up and down to "go get water" and get water into the grooved notched ring as it gets drilled. It is a hassle if you think it's a hassle. It's a pleasure and a source of personal pride if you think of it that way. It is whatever you say it is. Hth.
