"They did a good job and followed up quickly to install a riser. Good service at a good price. BUT... I was a bit skeptical of their recommendation for a new filter and expensive turbo cleaning of the septic field/components. I declined the recommendation. The septic field isn't showing any signs of a problem (soggy/soft ground). I might regret it, but I suspect they were needlessly upselling me."

"Septic system was full and back flowing into the basement. These guys came out within a day, located the tanks within minutes, found the problem and came up with a solution! They came by a couple times afterwards just to check the area and make sure everything was still draining properly. Very prompt and professional! Great job guys!"

"It is a privilege to give William Parrish Plumbing my highest recommendation. Our project included drain/flush of a tank-less hot water system and repair of a cracked toilet valve. The work was performed by Pedro who was personable, knowledgeable, and a true craftsman at his trade. He presented several work options so I could pick the service best meeting my needs. Pedro was efficient and extremely clean. You can't go wrong with these guys."

Septic Tanks questions, answered by experts

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.

The pressure in a well pressure tank should be set 2 to 3 PSI below the pump's cut-on pressure. The cut-on pressure is the lower number in the pressure setting (e.g., the '30' in 30/50 PSI) and is the point at which the pump starts. The cut-out pressure is the higher number, where the pump stops.

For example:

  • If your pressure switch is set to 30/50 PSI, the tank pressure should be 27-28 PSI.

  • If your pressure switch is set to 40/60 PSI, the tank pressure should be 38 PSI.

Common pressure settings for household applications include 20/40, 30/50, and 40/60 PSI. The difference between the cut-on and cut-out pressure is typically 20 PSI.

Since vinegar is a weak acid with a pH of two to three, it’s generally safe for septic systems. It won’t eat away at the good bacteria in your septic tank and can help break down the sludge, which is its bottom layer. However, like with everything in life, moderation is key.

A leaking well pipe is quite different from if the well itself is leaking. To seal a leaking well, pour a cement mixture or bentonite into the space between the well casing and the borehole wall. The heavier cement collects at the bottom to form a solid seal, pushing lighter materials like mud and fluids up toward the surface. Professional well installation companies have the equipment to do this properly. 

The ideal depth of a septic drain field is 18 to 36 inches below the surface. The trenches must be deep enough to allow proper wastewater distribution and filtration while remaining shallow enough for oxygen to reach the soil, promoting bacterial activity that helps break down contaminants. In areas with high groundwater or poor drainage, shallower systems like mound drain fields may be required.
