Some new low flow toilets actually do a decent job, surprisingly. I’ve been looking at houses for my mom, went into a renovated 40 year old brick ranch out in the country that had been thoroughly updated, the new toilets worked great, very pronounced “whoosh,” no need to flush twice at all. It had to have some sort of pressurization assist or forced air. No pressure tank on a wellwater system would do that, that I’m aware.
I don’t care if they do a terrific job. It’s none of the government’s business.
