Here is my situation:
Upstairs in my two story house early this morning, I opened a sink faucet tap. There was no water stream...just spitting and coughing. The downstairs water worked when I tried it, but then it didn't, sputtering out. It takes me a long time to figure things out, so maybe ten minutes passed while I tried. Then, when I opened a tap again, there was sufficient pressure in the system to create flow both upstairs and downstairs. I even took a moderately long shower. It was nice...the luxury a morning shower always is. Had I not observed the problem earlier, I would have had no suspicion that there was one.
After drying myself off, I tried the upstairs faucet tap again, just to reassure myself that everything was alright. No water came out...just spitting and coughing. Second verse, same as the first....
I cut the power to the water pump and to the water heater, went under the house, and drained the pressure tank, so that I could test its static air pressure...it was a little under by a few pounds maybe, but surely not enough to fail to push a stream of water through the pipes. I used a portable air tank to bring the pressure up to the recommended psi anyhow, just in case. What the hell do I know, anyhow?
I then powered up the system and watched the pressure gauge to make sure it was cutting out at the required pressure. It did...but then I observed a strange, slow, drop in pressure...from the 50 psi cut-off down to
40 psi, where it seemed to hold steady. I thought maybe I had left some faucet in the house in an open position, but when I went into the house to check, everything was off....When I went back under the house to re-check the status of the pressure, the gauge read 50 psi and was holding steady...just where it should be, standing ready to serve up water as soon as a tap is opened....With no appliances calling for any water for some 40 minutes, the gauge has held at 50.
So...I have no good understanding, really, of what exactly is happening. I'm focused on that slow, steady pressure drop from 50 to
40 when no taps are open...but that conflicts with the current status of it holding at 50...Was the slow steady pressure drop just a one-time thing?...Was it even significant?...What is going on?...(And, for those of you who find amusement in unanswerables...*Is* there any such thing as one-time thing?)To anyone kind enough to respond constructively to this query, please accept the appreciation of a man befuddled by both water and life.
