Water heater inlet valve? Pic included

the water in the house had slow flow on the hot side…cold side flow was
ok. Is this due to the valve being cut off ?


most likely

I’m surprised it had any flow.

that would sure do it

If there was flow the valve in Question had to be defective or there be a problem else where.

Looking closely at the picture, it appears that the ball valve may be ‘cracked’ open just a bit which would account for th every low flow. If I saw that in inspection, I would definitely open it some more to find out!:mrgreen:

I would not open the shutoff as it is closed for a reason.
I observe it also has Galvanized piping which has a tendency to close up over time.
