The severity of Work

How is the condition of your shut off valve? Is everything around it in good condition? Do you need any other repairs or replacements? 

These are important questions that we need to address. If you have a leaky pipe or any broken sections, your cost can go significantly higher. Make sure you get your system thoroughly checked beforehand.

Factor 1: Location of your Valve

Your main water valve is pretty easy to find. Follow along your main water line of the house until a knob or lever is seen. It’s likely to be in an outside wall or the basement of your house.

In older houses, finding the valve can be a bit harder. In that case, If you hear water running in pipes with no leaks, following that can work.

Your house will generally have a ball valve in place. An older house may even have a gate valve.

The position of your valves can change the final cost. If it’s harder to find, it’s going to be expensive.

Factor 2: Corrosions 

Once you’ve found your valve, look around to see any signs of corrosion. See if you find any sort of residue around your valve. If the residue doesn’t come off, there’s a chance that your valve is corroded. It requires a replacement.

If your valve has corrosions, there’s a chance that other parts of your system are corroded as well. And you need to fix the entirety of your system, thus hiking up the cost. 

The cost of an entire system replacement can go as high as $2000, based on other factors.

Factor 4: Shut off Mechanism

Try turning the valve on and off a few times to see the condition of the valve. If it’s stuck or the valve keeps turning, it might be problematic. It might have corroded and needs to be replaced as soon as possible.

An improper shut off mechanism can spike up your cost as well.

Required Tools

This isn’t important if you’re generally used to household plumbing works. But if you’re planning to start from scratch, you’d need some tools. Household tools like wrench, lubricants, etc. are an absolute must.
