So
You have a basement sink, and that faucet is leaking

By leaking you mean its slowly dripping when the facuet is shut off?

And there is no shut off valve to turn the water off?

Let it keep dripping.
Tomorrow turn the water to the house off, and replace the seats and springs of the faucet, or if its a shit faucet just replace the whole thing.

Its odd to not have a shut off valve, you can install one pretty easily and cheaply if you wanted to though.

wrap the end of the faucet in duct tape to seal the leak.

Yea it's a basement sink and it's all hot water. the last water bill was 2x regular.every 3 month period was ~80 m^3 but the last one was 120m^3

Mainly there's no shut off valve fro hot water from that faucet to the heater. Basement is unfinished so all the pipes are exposed. It's also not dripping it's basically pouring, when the hot water valve is off.

>Tomorrow turn the water to the house off, and replace the seats and springs of the faucet, or if its a shit faucet just replace the whole thing.

Any idea how much this might cost?

That doesn't sound like it's going to work...

Seats and springs for a Delta or Moen faucet cost less than 5$. Thats usually for a small drip, but maybe a real bad one could cause a larger leak.

I can find crappy faucets starting at 25-30$ at my local hardware store.
Its really not that hard to install them

Oh, and i should point out there are some cartridge based faucets that supersede seats and springs. You can just throw a new cartridge in, but you probably wont find those in a hardware store.
