Water flow, drainage and other processes are usually relatively quiet functions of your plumbing system. On occasion, however, plumbing can get noisy, creating annoying and sometimes alarming sounds that, while usually not serious, can be irritating.
One of the more common problems is a phenomenon called water hammer. This is a loud banging, clanging or hammering in your plumbing system when a faucet or valve is quickly and abruptly shut off. Quickly stopping the water flow in other appliances and fixtures, such as the dishwasher, the washing machine or a toilet can also cause water hammer.
Water hammer happens because quickly stopping the water flow creates a shock wave that travels through the pipes. If water hammer becomes very severe, it can cause the entire house to shake and even damage the pipes.
There are two main techniques for reducing plumbing-pipe noise and stopping the annoyances of water hammer:
- Install a water hammer arrester in the pipe network. This device is equipped with an air-filled chamber that absorbs the shock waves.
- Install a pressure tank similar to those used in rural homes for pulling water out of a well, cistern or lake. Use a 5- to 8-gallon diaphragm tank with an internal rubber membrane separating the air in the top half of the tank from the water in the bottom. The air behind the diaphragm absorbs the shockwaves that cause water hammer.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
