We offer turnkey solutions for both residential and commercial customers — no job is too large or complex for our expert team.

"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."

Septic Tanks questions, answered by experts

The right psi for your well pressure tank depends on the tank’s pressure settings. For instance, if yours is set to 30/50 psi (which is common), the ideal psi is 2 to 3 psi below the cut-on pressure—in other words, 27 to 28 psi. However, if it’s at a higher setting of 40/60 psi, 38 psi would be the appropriate level.

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.

Yes, you can pump a septic tank too much. The ideal pumping schedule varies based on capacity, water usage, and household size. If you pump the septic tank more frequently than your recommended pumping schedule, the beneficial bacteria can leach into the drain field, causing an imbalance and solid waste build-up.

Mound systems can fail if foreign objects are flushed into the septic tank, the septic tank is backed up with solid waste (sludge), if wastewater floods or seeps from the mound, or if any part of the system is clogged. To prevent this, only flush toilet paper and your normal “business” down toilets, and get a septic inspection at least yearly.

Beyond the type of well pump, there are a few other factors to consider when selecting a well pump. Keep in mind the depth of your well, your average water usage, and the PSI of your water-consuming appliances to determine the appropriate motor horsepower and size of your well pump.
