Does my toilet flange need to be replaced?

It looks remarkably well, considering the age it must be. There are no signs of leaks. You didn't indicate you had any leaks. I would add a couple of nylon shims under the ring and screw it to the ...

How can I prevent suds from spewing out my toilet?

How long do modern flush toilets last?

It is always hard to say whether new things expected to last 100 years will last as long as the ones made 100 years ago. Sometimes in hard water areas very old toilets become so calcified internally, ...

What size flexible toilet supply line will fit my shut-off valve?

I would buy one of each (3/8" and 1/2"), take them both home, and see which one screws on. Once you know what size you need, return the other one. If, by some rare chance neither fit, return ...

No, an RV toilet does not use a trap. The valve in the bottom of its bowl serves the same purpose (that of blocking sewer odors from rising up out of the waste plumbing/tank). Note, however, that you ...
