What are these?

Pretty sure these pipes run up to my kitchen faucet. These look like saddle valves but I don’t think they are?

Can I install a bidet on this ?

Are there sewer flex lines for connections where soil/foundation sinks? Driveway is sinking and pvc keeps getting disconnected.

It hasn’t rained in months in Texas and my driveway is sinking some. My sewer line from the kitchen is disconnected so water is draining straight to my driveway. Is there a flex hose or something I could use for the connection from the house to the ground line that would be able to handle the soil movement?

Curious

I was having a cocktail at a local establishment and saw there gas meter on the patio. If someone was to turn the blue valve handle would it shut gas off to the building? Just wondering why this area isn't behind a gate.

Drain on hot water heater.

I have been given the go ahead to drain our unit’s electric hot water heater, which is definitely full of rust,iron, dirt etc. I have watched lots of good tutorials… but how does this grey plastic drain valve work?

Is this normal? Water is yellow coming out of the tank… In valley county Idaho.

Hot Water tank leaking - can’t figure out where from?

Hear a dripping sound from the machine but can’t figure out from where? Checked the top and am the values - all are dry, looks like leak is from the bottom but hear a dripping noise like it’s falling from a small height. All the plumbers are off this weekend in my area. Water is touching furnace as well. Is this an emergency? What should I do?

How do you know what shower cartridge to buy?

Got me a rusty shower cartridge. Apparently it needs replacing but I don't know how to tell which cartridge is the right fit! I've contacted the manufacturer (Grohe) but it might be quite the wait to hear back. Any tips on shower cartridge identification and where one even buys such a thing? Woulda been cool if they'd thrown a modem number on this sucker...

Need help with brown sulfur hot water

I was gone for almost a full week. I am on city water, but it’s a very small town. House is just over a year old. It’s been 100 here almost everyday for the past 2 months. Do I just need to empty out the water heater and refill it a few times to clean it out?

Bathtub leak from my new tub

I had a new bathtub installed a few months ago and just used it for the first time. It is leaking below into my basement. I found a bad rubber gasket on the new pvc that was installed. Should I be asking my installer to fix this? Also, how easy of a fix is this? Is this something I can fix on my own from below in the basement? Picture attached!

T adapter for a bidet is too large for existing hoses/pipes and I can’t find a solution/adapters that would work anywhere

Not quite sure if this fits this sub but it’s my best bet unless someone can direct me elsewhere. My problem is a bought a bidet for my old house and it worked great. But when I moved the new toilets existing pipes/hose are too small. And looking online for any kind of adapters or even a smaller bidet yields no results. If anyone can tell me what I need to buy and where I could find it I’d be great full. The T I’m holding in my hand was 1 ich or 15/16 on the visible ends and smaller on the part that goes towards the bidet, and the house pipe/toilet hose are about 1/2 inch
