Briggs R-7240 Tank

Can this tank be replaced anywhere....HD & Lowes do not carry Briggs? Anywhere else? Online?

If it's a 3.5 gallon tank from the 80's then no.

The best you can do is find a Briggs that someone is throwing out, or buy a new complete toilet.

You would be replacing a builder grade $80 toilet that is decades old.

I believe that is a 3.5 gpf from the late '80's. There is NO tank which will bolt up correctly, or even if managed to getit on there, it wouldn't flush. Your bowl was really designed for 5 gpf, and they just reconfigured the tank to meet the 3.5, and those toilets never flushed right. If you tried to flush with 1.6 it would laugh at you,.

Might I respectfully suggest you explore the Toto line of toilets? I know you are hoping to find an inexpensive fix for your problem, but you really have no viable options. Yes, you can buy another builder grade toilet for $100 from the box stores, but these are not good performers, and when you consider a toilet will be used by every member of your household several times each day, everyday of the year for the next 20 to 30 years, why would you want a toilet that would require frequent plunging and not always clear the waste when flushed just to save a few dollars?

Thanks guys. Have to squeeze it in between games and races this weekend!

i have a briggs conserver toilet and it says 't brinks' in the tank. I wonder what would happen if you use a pressure assist on a 3.5 gpf toilet? will it work?

No. A pressure bowl is differently-designed than a gravity bowl. The water will spray out of the bowl and go everywhere. If you try a gravity tank on a pressure bowl, the water doesn't even drain from the tank.
