What is the pressure of your water system.
Is this something new, has any plumbing work been done lately?

Somewhere between 40 and 45 pounds

Yes but don't know what my boy did it

OK, is this something new, has any plumbing work been done lately?

Old house no waters been on for 2 years or longer

Suspect something partially obstructing pipe between valve and tub spout.

If the shower head screws on to the shower arm, get a 1/2 pipe cap, iron or PVC. Remove shower head and screw on pipe cap. Open faucet and see if you can clear pipe (with spout removed).

If shower head does not screw onto arm, purchase 6" black pipe nipple and cap. Remove shower arm and screw in pipe nipple and cap.

When reinstalling shower arm use plenty of pipe dope.
