In the morning I have water pressure at first use, then it stops and in a few min it starts up again. I have a 6" well with a 1/2 hp surmergable pump and pressure tank.

Thanks

Let's check out the bladder tank. There are several ways to check your tank. It has a air valve on top like a valve on a tire. Push it in, you should not get any water out of that valve at all. Another way is to tap the tank from the bottom up. You will hear a "clunk" on the bottom filled with water, however you should hear a "clang" near the top filled with air. If you have water up to the top the bladder has ruptured and the tank must be replaced. To set the air pressure in a bladder tank, look at the cut-in pressure on your pressure switch. Now drain the line down with the pump off. When there is no more water coming out of the hose bib that you drained the system down with set the pressure in the bladder tank at 2 lbs. below the cut-in pressure. Check it with a tire gage. If your pressure control is set to come on at 20 PSI and go off at 40 PSI then your gage should read 18 PSI. Hope this helps and thank you for rating my reply

WT, do what Speedball suggests... good first start. If that does not work, then you will need to eyeball your gauge as the system goes through this. When you are getting no water, then your gauge should be dropping down to near zero. If that is the case, then the pump is not cutting on in time. That could be due to a blockage in the little pipe which leads to the switch. This will cause a lag in the pump cutting on, so if the pump is supposed to cut on at, say, 30#, instead the switch does not cut the pump on until it reaches maybe 12#. BTW, you can do this at the same time as you check out your pressure tank.
