The "grubby" took the pipe off the top of the tank, it was clogged a little and so he cleaned it out and put it back on. He stated that there was no tube in the hot water tank, where he took the pipe off. Now when we turn the hot water on, itcomes out good and then dies down to nothing. Help me please before I have to go and rent a hotel room just to take a shower.......

 

Did he get a gate valve turned on all the way?

 

we have no valve on the hot water tank, he stated he had to turn the water off and on from the mian line, which he said he did...

 

You may have a cold water supply dip tube that has deteriorated and is clogging the hot water outflow pipe. Did he say that there was no dip tube?

 

Thank You oldguy for answering, he said the hotwater line going into the tank (water heater) has no pipe in it like it shows in a book we have, He said when he puts his finger down into the slot where the pipe goes, he feels hot water and no pipe. The cold water line seems to be fine, he says.
because the water coming out of the faucets is good.
helpppppppp oldguy, pleeze
Update: so far he has cleaned the hot water lines coming from the tank. They are galvanized pipes.

 

I will have him check the cold water supply line, dip tube and let you know the results. If it is clogged should we replace it or clean it out if we can?

 

The dip tube carries the cold water supply to the bottom of the tank. It can be replaced. You should see it in the book.
There is no pipe sticking down at the hot water outlet.
The cold water coming out of the faucets has nothing directly to do with your heater. The heater should have its own cold water supply line as a branch off of the main cold supply line. The cold water pressure going in controls the hot water pressure going out. One or the other lines appears to be restricted.
Galvanized pipes? Those are notorious for scaling up inside over time, and even eventually plugging up completely. That may be your problem, and you may need to replace the lines into and out of your heater far enough to get rid of the restriction.
Good Luck!
