Question

old valves...can i / should i turn them??


first photo is a shutoff valve (on the left) from the street; pvc (?) to pipe into the house. likely 22 yrs old and i'd suspect has never been used. (the valve on the right is closed and goes to the house but nothing on the other side).

thoughts on trying to close & open it - to make sure it works...to make it work or should i just call it a day and replace it? can i break it if i try to force it closed or can it get stuck part way or closed? (that would be a real drag).

2nd photo is inside the house. red handle is inside shutoff valve - same questions as well. 3rd photo is inside the house, yellow handle is closed and the end of the pipe has a threaded fitting for a hose - to drain the house. wisely it's been wired shut and i put a cap on the fitting.

thanks!

Jim

With some penetrating oil like pb blaster etc they can be exercised if you wish.

Imo, I don't see any leaks and you have good water pressure, I would leave them alone. Why go looking for trouble. Just my opinion.

Additionally, if that is from the street (curb valve) as you say, that is not yours. That is the municipalities. So if there is ever any trouble with that valve, they will take care of it. At least that is how it is in my municipality. Check with yours first to find out.

Just leave it alone.

Ball valve are pretty tough and long lived but even so, I never kick a sleeping dog. At the very least, you'll release a bunch of accumulated deposits into the line and they may end up stopping up something in your house that will cause you more work.

Aerators, ballcocks, shower heads and ice maker are some of the devices that may not be able to digest that crud. No fun taking them apart for cleaning.

As @surferdude2 stated, any other valve than a ball valve, is prone to failure. Ball Valves are much more durable.

One of the worst valves IMHO is the gate valve. Because part of the mechanism that closes and opens it is immersed in water, it has a tendency to either rust completely through or be weakened enough so that it breaks when you need it most.

When ever possible, I change over every valve in my the house to a ball valve. This includes shut off valves to fixtures and sill cocks. If it says they are multi-turn it is not a ball type valve If it says quarter turn, it is.

Also, look for full-bore or full stream valves. That means the ball portion of the valve is the same size as the pipe it will be attached to.
