Customers say: True professional

"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 have used the Drain Co. several times. The work is always solid and reliable. They appear to have raised their prices though as last year it was $172 and this year $262 for 3 drains. The guy was here for roughly 2 hours. Last year it was 1.5 hours. I would have preferred knowing ahead of time the cost rather than being surprised by the bill, especially given that we are repeat customers and had an expectation that the cost would be equivalent to last year since our yard has not changed."

Septic Tanks FAQs, answered by experts

A septic tank riser should extend to just above the ground level or slightly above it. The exact height can vary depending on local regulations and personal preferences, but a common guideline is to have the riser's top flush with or no more than a few inches above the surrounding ground. This height allows for easy access to the septic tank without creating a tripping hazard or obstructing mowing and landscaping activities. It's essential to ensure that the riser lid is easily visible and accessible for regular maintenance and inspection while being mindful of safety and aesthetics.

Septic tanks and cesspits are both types of sewage and wastewater systems, but they differ in key ways. The main difference between the two systems is that septic tanks separate sewage from wastewater and allow the latter to flow into a drainage field to filter and disperse into the soil. Cesspits don’t have outlets and instead, store sewage until it needs to be pumped by a professional.

Certain foods are easier on your septic tank than others. Septic-safe foods include yogurt, fruit, cooked veggies, and bread because these items all break down relatively easily and can pass through your system safely. Rotten tomatoes, specifically, are actually good for your septic tank because they can increase the amount of good bacteria in the system. 

Getting well water tested costs $100 to $350 if done by a pro. You can also buy DIY test kits for $20 to $100, but professional tests are more reliable. You can get a comprehensive well inspection, which includes advanced water testing, for $700 to $750, which you should do yearly anyway.

Most well pump pressure switches have a factory setting of 30 to 50 PSI. There’s some flexibility with this if you’d like a lower or higher water pressure, but remember that it should sit 2 to 3 PSI above your well tank’s general pressure setting.

The inside of your pressure switch cover will usually indicate minimum and maximum settings—going below and above the numbers might damage your well pump.
