Loosen 1990s Kohler handles?

My washer machine all of a sudden started leaking like CRAZY when in use.

My husband seems to behave it’s a hose or something that he can fix himself. Now don’t get me wrong the man is super handy and has general knowledge about all home repair issues, but I’m worried this is going to require professional help or just a brand new one. What you can’t see is that it’s started leaking so bad the carpet is half way soaked, just now it leaked in a completely new direction it never has before getting all the whites laid out to be laundered soaking wet. Every use it gets way worse. Please help me have a better understanding of what maybe wrong and the best course of action!! I wanna let my husband try, but not if it’s just going to lead to a worse situation. If we can avoid getting a new one that would be preferred seeing as we just had our first baby 8 months and are desperately trying to save in all places we can! Thank you for any advice and suggestions!! It’s much appreciated!

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?
