When the pump come on (at 35 psi) water will enter the tank and squish the air toward the top of the tank until the pressure switch senses 55 psi when the pump shuts off. When someone turns on a tap, water will flow out of the tank, being pushed by the compressed air, until the low pressure point is reached and the pump comes back on. With a pressure tank as big as ours should take quite a while (except for the building heat system which demands a large volume). Our pressure tank, unlike those in most private homes, has no bladder. The function of a bladder is to prevent the pressurized air from slowly dissolving in the water until there is little or no air at the top and the tank becomes  waterlogged . A waterlogged tank causes the pump to cycle on and off excessively and the pressure in the building surges and fades quickly. Because of the lack of a bladder we will have to periodically recharge the system with air. Ideally, a pressure tank should be purged of all water then air pumped in at a pressure 5 to 10 psi below the low (pump on) pressure switch setting. Thus, the tank will be nearly empty of water when the pump comes on and there will be a maximum volume of air to compress thereby assuring maximum water storage. However, in our case that procedure is not really practical because the purging process would inject air into the buildings plumbing. With our long pipe runs it would take forever to clear out the air (with a lot of spitting and sputtering) and it could possibly have an negative consequence to our heating system. To re-pressurize our tank: To properly pressurize our tank without loading the plumbing with air, start by plugging in the air compressor and let it charge up until it shuts off. (The on-off is a red push-pull switch on the regulator.) Next, check the output pressure on the compressor and make sure it does not exceed 75 psi. (psi is the little scale in red inside the black scale. Put on your glasses, it s hard to read!). Do not skip this step, the pressure tank is rated for 75 psi max, and the compressor is capable of much more than than. The tank could explode violently if over pressured! Next, go to the building thermostat and turn it down so the heating system won t call for heat during this procedure. (The pump won t keep up with the demand making it impossible to properly set pressures.) Now go to the breaker box and turn the water pump off. It is a double pole breaker on the right hand bank about 2/3 of the way from the top. On your way back to the pressure tank, turn on the cold water tap in the kitchen sink and both the women s and men  s lavatories. You will see the pressure gauge on the tank dropping the rate dependant on how much air is left. Connect the air chuck to the air stem on the tank. (Make sure the compressor has been charged and is on and ready to go. If the compressor pressure drops below that of the tank water will flow backwards through the airline possibly damaging the pressure regulator.) The pressure gauge on the tank should start upwards. Let it build to about 45-50 psi, if it goes above that simply pull the air chuck off for a while. You should hear air bubbling through water inside the tank. Continue adding air until the bubbling sound stops indicating the water level has dropped below the level of the air stem. Once the bubbling stops, continue for another minute or two making sure the pressure is 45-50 psi. Disconnect the air chuck and we re done. Turn off and unplug the air compressor, shut off the open water taps, turn the pump back on, and reset the heating thermostat. Enter the date on the sheet provided for that purpose. Little or no air, but still under 35-55 psi pressure Air stem To everything From Pump Pressure switch A properly functioning pressure tank A  waterlogged pressure tank Pushing water out - replacing it with compressed air Air hose and chuck To everything From Pump Pressure switch Listen for vigorous bubbling inside tank Testing for waterlogged condition: Using a small tool (a matchstick, whatever) push in the air valve and you should get air - not water. (Persist for a few seconds as there may be some water trapped in the tube and pressure switch.) If you do in fact get water and the pressure is near the high end (55 psi) it is possible that the water level is above the air tube but there is still a satisfactory quantity of air in the tank. , Bleed off some pressure by opening a water tap and check again. If you still get water as the pressure drops below 40 psi or so, it is time to recharge the tank with air. Note: The building heating system uses about all the water the pump is capable of pushing through it. While the heating system is on the system pressure as seen on the pressure tank guage will stabilize a bit above 40 psi and remain there until the heating system shuts off. The short version& Once you have read and understood the previous pages, you can use this short check list to re-pressurize the tank. Plug in and turn on the air-compressor until fully charged and it shuts off aautomatically. Check the output pressure at 75psi. Set building thermostat down so heating system does not come on. Turn the water pump off at the breaker panel Turn on the kitchen and both women s and men s cold water taps. Connect air chuck to the pressure tank and maintain pressure at 45-50 psi while water is pushed out of the tank by temporarily removing the chuck when the pressure goes above 50 or so.. (Do not set the compressor regulator below 75 to accomplish this as a reverse water flow down the airline could result.) It will take quite a while to fill if the tank is completely waterlogged. Listen for the bubbling inside the tank. When it quits make sure the pressure is 45-50 then continue for another minute or two. Disconnect the air chuck Turn the open taps off Turn the pump back on at the breaker panel Return the heating system thermostat to  program condition: Using a small tool (a matchstick, whatever) push in the air valve and you should get air - not water.
