I need help and I'm not sure where to turn

My husband seems to have a problem with OCD and it is causing me problems.

In the morning we get up and he gets dressed and when he's ready to leave he insists we check the water. off. If I don't go he says "come on, please " until I do. He insists I go into the bathroom with me and ask me if the water in the tub is off.
Then the water in the sink. Sometimes, he wants to go back and check again.

Then the kitchen. We have to check the sink and the stove.

He also has to stare at the washer and dryer for a while and sometimes check various electrical outlets. Today he left the house and came back 15 minutes later and insisted I check the water again. He doesn't think it's a problem. We don't currently have insurance. What can I do?
