No. Close off the main at the tank and add air (around 35 psi).
Mine came new with air pressure in the bladder & no water in the unit so I would assume that you would pressurize the bladder with no water in the unit . Hope this helps .
Mixer valve
If you are talking about a normal house, all you need to do to 'pressurize the system' is turn on the main valve, then open up each tap/faucet in turn until water is flowing freely.
Short, layman's answer- A pump at the top sucks water or one at the bottom pumps water up. This water goes into a rubber bladder in a pressure tank pre-charged with air that cannot escape. This air gives the household pressure as it forces the water out of faucets as they are opened.Short, layman's answer- A pump at the top sucks water or one at the bottom pumps water up.

You have to undo the aerator at the end of the faucet and clean the screen or plastic water saver out. It will be plugged with sand or sediment.
Typically, towels, soap, and water faucets can be found in a bathroom.
Temperature balance shower body needs to be adjusted
Generally the pressure in the tank air bladder should be 2 psi below the water pressure switch kick in (pump turn on) point. In this example of 48 to 68 Lbs the air bladder pressure should be 46 psi. This pressure should be measured with the tank empty of water, that is to say NO water pressure applied. NEVER over pressurize the air bladder - it would be better to under pressurize if in doubt. Some tank manufacturers may recommend a different PSI differential so check with the tank literature or the manufacturer.
old pipes in the sink or tub upstairs
The easiest answer I can come up with is that you have a filter that is completely clogged up. Usually with filtration, the outside faucets are before the filtration so you don't put filtered water on your plants and grass etc.
Their Faucets
There is a hot/cold cross connection at one or more of the faucets at you house. make sure all faucets are shut off both hot and cold. If it still occurs more than likely you have a Moen faucet somewhere (most likely).
