"When our septic pump stopped working I called Superior Septic. Angel came out and figured out the complicated problem that could have eluded someone with less experience, and skill. I am impressed with how fast he fixed our pump. I highly recommend him and his company."

"Our landscaping in Menlo Park needed a complete refresh. The team replaced thirsty plants with drought-tolerant options that still provide plenty of color and curb appeal. We're using much less water without sacrificing appearance."

"I hired Clint to replace our entire septic system and was very happy with the experience. I am renovating my home remotely from across the country and needed someone who was a good communicator, trustworthy and did quality work. I feel I got all of that from Clint. He was very easy to work with throughout this entire process. He helped me navigate what system was best (and most economical) while getting the county approvals. His pricing was straight forward and there were no surprise expenses that typically come up when using other contractors. In fact, Clint took on the cost for a tank upgrade and did not pass that on to me. He also seems to be well-liked at the Napa County building dept. which is another good sign. I recommend to anyone looking to replace their septic system to reach out to Clint Pridmore Construction."

Septic Tanks FAQs, answered by experts

Installation necessitates professional expertise due to complexity and to ensure safety when handling waste.

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.

Yes, you can adjust your well pump pressure relatively easily by yourself. You’ll need to remove the cover from your pressure switch and adjust a nut that controls cut-in pressure. Learn more about how to adjust a well pump pressure switch with a step-by-step guide to setting your water pressure.

Yes, a bigger well pump can increase water pressure—up to a point. If you currently have a well pump of 8 GPM, you might notice a pressure boost when you go up to 10 GPM. However, overshooting significantly (going up to 15 GPM for an 8 GPM home) can strain your well system and result in things like burst pipes that can decrease your water pressure and make for costly repairs.

A household of four can easily fill a 1,000-gallon septic tank within a week. It may be 10 to 14 days for smaller households. But the reason why you don't need weekly pumping is because the tank's contents eventually reach the overflow pipe. They flow down this pipe to the absorption area whenever water is used in your home. The tank keeps working at this full level until it's pumped again.
