Live in a large 2 story apartment complex. The building is about 10 to 15 years old. Neighbors upstairs, insert a devise that renders me without water, or marked attentuation of water of any significant pressure. The maintance people here are perplexed, when the devise is removed normal pressure is resumed. I often hear wrenches, plyers and tools inserting this devise. Each unit in this bldg has 2 full bathrooms. Affects entire apartment when this devise is inserted. I have heard them say it is illegal. Has anyone heard of such a bizzare situation. The water pressure so profound, awakens me, can hear thru out entire apartment. Like Sheds Fountain upstairs. often leaking down into my bathroom. Sorry, not much info, hope enough to solve this mystery. Driving me nuts.
I imagine a hydroponics farm takes a lot of water to fill, so the pressure would drop as the wide open fill kept the water flowing. A hot tub or other large use off the main would drop the pressure while in use. You might need some ceiling reinforcement to hold the extra weight above your head.
