Preferred Professional Plumbing
Preferred Professional Plumbing
Preferred Professional Plumbing comes with over 10 years experience in the plumbing industry. Your satisfaction is our goal. We take pride in our materials and craftsmanship.
"This is the third time we've used Preferred Professional Plumbing in the last couple months. First, Grant and his assistant came out to replace our hose bib, the part that provides water to an outside spigot. While they were on that visit, I mentioned we'd need to buy a new kitchen faucet. He took a look and suggested we call Moen and ask for a warranty replacement. That saved us from buying a $300 faucet. He came out the following week and installed the new faucet. Both of those visits were great. Then last Friday, our 75-gallon water heater died. I called Grant, and he said he'd be able to get out the next day to replace it with either a new tank, or a tankless model. We opted for the tankless one for unlimited hot water. He again showed up on time and got us hot water with some temporary connections... you never realize how much you miss hot water until you don't have it. He came back twice more to run all the permanent water, gas, and air lines. He's a real artist with piping. I'll attach some pictures so you can see how neat and tidy the installation is. I heartily endorse Grant and Preferred Professional Plumbing if you want a job done right!"

Deciding between an engineered septic system and a conventional one depends on property size, soil quality, local regulations, and environmental factors. If your property has limited space, poor soil, or is close to sensitive environmental features, an engineered system may be required. Professional site evaluations, considering water usage, long-term plans, and budget constraints, can help determine the appropriate choice. Consulting with a septic system professional is crucial for ensuring compliance with regulations and selecting the best system for your property's unique needs.
A septic tank should be pumped once every three to five years or sooner if there’s a problem with your plumbing backing up. A large 5+ person family who frequently has guests over using the bathroom or who pours a lot of water and food down the garbage disposal may need to get it pumped closer to every two years.
Many septic professionals agree that spring is the best time of year to empty a septic tank. By this point, the temperatures have usually warmed up enough so that the ground is no longer frozen, which makes it easier to access the tank (and less likely for the waste to be frozen inside the tank). Summer and fall are also decent times to do it, but winter isn’t.
A septic tank with a 1,500-gallon capacity is good for larger homes with up to 6 or 7 bedrooms. The average home can go with a smaller tank, about 1,000 gallons, which supports a home size of up to 2,500 square feet, or a home with about three bedrooms.
Anaerobic septic tanks are the most cost-effective type of septic system, with an average cost of $3,000 to $8,000. Sand filter septic systems are the next most affordable, ranging from $7,000 to $18,000. Mound systems have the highest price tags of the bunch, coming in at $10,000 to $20,000 per installation.
