We have an older house, on top of it being an older house the people that owned it from the time it was built were also the most Jerry rigging asses I've ever seen in my life.

So this afternoon I'm replacing a faucet in the master bathroom. First off, since we moved in the hot water has been on the wrong side. No big deal, I'll swap it when I change the faucet.

First problem, the supply valves are half inch instead of the normal 3/8. Then the faucet side of the supply valve was a male end, not super common but of course not what I needed and my fault for not getting new supply lines.

Well I already have every torn out, and didn't feel like going to the store so I go check other bathrooms. Sure enough, there's a 1/2" to 1/2" supply line in one. So I turn off the shut off and pull that line. Bring it into the new install and just hook up one side so at least both have cold water and I'll fix it tomorrow.

Open up the valve for the supply line that I hooked up, water shoots out of the other valve.... WTF. After an hour round trip to Home Depot (we live in the sticks) who didn't sell a 30" 1/2" to 1/2" supply line, so I had to get adapters, we are up and running.

How in the hell does water come out of the opposite supply line when the opposite valve is turned on?

The joys of plumbing! Anytime I undertake a plumbing project I plan on three trips to the plumbing supply store at a minimum!

And it's almost a universal thing that if fooling with drain lines, be prepared to chase leaks past the point of you needing the initial repair.

If it's a single lever faucet that's just how they work. If it's a two lever faucet as long as only one side is open at a time you shouldn't have that issue. Also, pretty much every angle stop ever is male compression threads on the supply side. Not sure I've ever seen female threads on one.

Most newer faucets/showers etc have balancing valves in them, so you have to use a compression tee and hook it to hot and cold side of the faucet even if it's just using one or the other. If you hook up just one side on a newer faucet it'll either spray water in the cabinet or not work at all.

I messed with it again this morning. Completely disconnected, both valves closed, if I open the left one, water shoots out the right one that's still closed.

I'm not even sure if that's actually possible.

Works fine when hooked up. Oh well.

I feel you man. We inherited a house that belonged to my in laws. My father in law was a Mr Fix It, but he really wasn’t that great at it. So every time something breaks and I investigate the repairs I find all types of Wild shite

The shut off valve for the water line to the refrigerator was in the wall and could only be accessed by knocking a hole in the wall under the adjacent room (bathroom). We ended up having to repair plumbing in the wall and found even more weird shite. Tore it all out and replaced it and added a valve shutoff for the fridge under the new bathroom sink.

The plumber was like man, I’ve never seen anything like this. Can’t wait until I have to repair the drain line in the master bath. Probably will require tearing up slab.

We moved to the middle of nowhere and early on we had many a project around the house to do.
This was my biggest complaint about where we live.
But, no complaints now.
Still may have to do a long round trip for a part, but it's not that often anymore
