Richard helped a pair of homeowners with low water pressure. After determining that there was nothing wrong with the city water main coming into the house from the street, Richard recommended installing an electric water pressure booster, which consists of a pump and storage tank. Richard started by shutting off the main valve and draining all the water out of the supply pipes. Next, he ran new copper pipe from the water main to the pressure booster. Then, he ran pipe from the booster to the main line that feeds all the water fixtures in the house. When all the plumbing work was done, electrician Brian Bergeron connected the pressure booster to the main electrical panel using armored "metal clad" cable. The booster system required its own circuit, so Brian also installed a new circuit breaker inside the panel.
