I have a large 2 story house that has a pond for water supply. Part of my filtration system are a sand filter and a graphite filter. With this system I have good water pressure on one faucet. As soon as you turn on a second faucet it goes to 1/2. How would you set up this pump and is it the best fix?

The pump detects pressure fluctuations in the system and automatically adjusts the flow. It is installed in line with the main water supply line at the ground level.
