Plumbing in the Home/fluctuating pressure when watering


When I am watering or just taking a shower the water pressure will increase when the well pump comes on. I can fell the increase or decrease when the well pump cycles on and off. What do you think. Thanks

Your tank is waterlogged.  Meaning it's full of water and all the air has escaped.  You can't compress water so when the air leaves, the pump over comes your use of water but has nowhere to go so it builds pressure, shuts off, loses pressure and turns back on.  The less air, the quicker it comes back on.

I am a Water Well Driller and Water Pump technician. I own a business in Riverview, Fl. We repair motors and pumps in shop and in the field. We repair and replace submersible and jet pumps, galvanized and bladder tanks, and their controls. Water filtration is another one of our specialties.


I started drilling and repairing wells and pumps with my dad in 1958 at the age of 13 years. I worked with him on weekends and in the summer when not in school. After graduating high school, I worked for my Dad until going into the Army in 1968. I spent three years in the Army then went back into the Well Drilling/Repair field.

Many Forums including my own.

High school and a few courses after getting out of the Army. They were offered on the GI Bill.
