Good day everyone. I have a photo available here: [[url=https://photos.app.goo.gl/bHzgyC9YBVYEYr2KA]photos.app.goo.gl[/url]] Right click on link, open in a new tab if using chrome. (it's essential to understanding the situation) [ATTACH]103920[/ATTACH] What I am trying to do is replace the faucet at #4. #6 is the shut off for the whole house #5 is a Goulds Well Pump #4 is a 1/2 inch faucet (old one shown - it leaks) #3 is the pressure release for the pressure tank #2 is a rusted/stuck square value/nut (I tried to turn it - won't budge - worried about stripping or breaking it) #1 is the shutoff for the pump into the pressure tank I am trying to release the pressure for a minute or two at #4 so I can replace the faucet. However, when I drain the pressure tank by opening the valve at #3, and prevent tank refilling closing the valve at #1, when the tank's pressure gets too low, the pump comes on, The pump appears to "heave" over and over. a) I am worried I will lose the prime and b) I am worried about damaging the pump. Question to everyone: Is there a way to avoid a blast of water coming out at #4 or is it ok to let the pump heave for a minute or two? I could turn off the power to the pump for a couple of minutes, but I am worried about losing the prime. Getting the prime back was done once previously - it took hours, and a plumber did it, and I really really want to avoid that situation. Any suggestions or recommendations?

We are helping out a family that moved here from MT. They bought a house with septic and, while talking to wife yesterday, mentioned that something in septic is running all the time. First thought was - pump is running non stop. I went there today - they have never seen septic before - and found as follows: 1. 3 chamber septic with normal sump pump, leach field and digital control pad. No water running from house to tank 1. 2. No filter 3. Constant water flow between tank 2 and 3 (pump tank) 4. Grey box sitting by bedroom wal, buzzing loudly non stop. 5. 2nd control panel, apparently for that box, both septic and that panel on common breaker. 6. Buzzing box plugged into the wall outlet. I pulled plug out and it shut down. Problem is, woman that sleeps in bedroom behind that wall can't sleep at night. She is recovering after major health issue and is very sensitive. I found that that box is apparently aerator pump for septic systems. Fine. Here's questions: - does it have to run all the time? None of our septics have that system and does just fine without aeration - can it be, if just must run, set on timer, so that it runs during the day and not during the night? - that's a lot of panel for simple aeration pump. Anything else it is controlling? - why there is constant water flow between tanks 2 and 3? See pics attached. [url]https://drive.google.com/open?id=10WIA87mnWcmRD4IoLmo6MNEP1hHXxisz[/url]
