How long do modern flush toilets last?

There are reasons to replace a whole toilet, but generally, if it was a functional toilet, it can remain one for many years. I replaced a functional 40 year old toilet with one that used about 1/3 the ...

What should I be aware of in buying second-hand sinks and toilets?

I applaud your effort at frugality and environmentalism. The "throwaway" mindset peeves me to no end. Many folks change out fixtures just to change the look or size, and there are plenty of good units ...

How do I tighten this bathroom faucet?

Outside hose bibb with very fine thread?

What you see there is a vacuum breaker spigot with its pants down. You'll need to try and procure the parts or just replace the whole works. More on that

Can't re-attach bathroom sink drain pipe

Time to cut your losses... As little as a new P-trap assembly costs, it might just be worth going to pick one up and replacing everything here. As noted elsewhere, the metal nuts will chew up the ...

Can Teflon thread tape be reused?

I agree with Ed Beal that you should replace it, but if you're in a pinch you certainly can reuse PTFE tape, assuming you recover enough of it and it's not totally shredded. Carefully unwrap it and ...

What should I replace this broken condensate line connection with?

That is a simple brass hose barb. I'd carefully unscrew it from the pipe, being sure not to twist and damage the PVC. Then I'd take it to my local hardware/big-box store and purchase one in a matching ...

Can't re-attach bathroom sink drain pipe

First off, it's a bad idea to use metal slip-joint nuts on plastic drain parts which most certainly didn't come with metal nuts. Slip-joint nuts are not all the same, and are not necessarily ...

How to use alternate flush mode on toilet

It's not an alternate mode, per se. Those values are the minimum and maximum tank volumes based on float setting. [Correction: These values seem to apply to High Efficiency (HE) and Ultra-high ...
