flush 2x? Long way to sewer main
Our house is 300' (uphill, fortunately) from the sewer main. We have a 3.0 gallon/flush toilet, because the plumber told my husband (twenty years ago, when he built the house) that he'd need to make sure we had a lot of water going down to wash solids all the way to the sewer main.
Now the top of the toilet tank is broken, and I can't find a replacement (because they evidently don't make tanks that big any more). I can't find a replacement tank, either. It's a two-piece American Standard toilet, in white; nothing exceptional, but it is a 3-gallon tank on a 20-year old toilet...
Please note, in the 20 years since the house was built, we've (knock on wood!) never had a clog in the pipe down to the main.
Here's the questions:
1) do we REALLY need a 3.0 gpf toilet?
2) is there some supplier, somewhere, who might have a replacement tank top? Or replacement tank-and-top?
3) is there some fixture manufacturer who still MAKES a 3.0gpf toilet?
4) what kind (if any) of new, low-flow flushing technology will reliably get the solid waste from the bathroom to the sewer main?
Thank you in advance--any expertise is appreciated!
