"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."

"Mike was called to clear an untimely (let alone super nasty) clog and backup in my home's sewer system around 11:30 PM on a Saturday night. It was a stormy night and he was out quickly to take care of the clearing of the (yuk) debris and digging out of a secondary driveway drain that was filled with other debris left by a construction crew doing some work on my driveway. Mike cleared out the drain area and the overflow area too. 5 stars all the way!!"

Septic Tanks questions, answered by experts

Your septic tank naturally contains the good bacteria it needs, so you typically don't have to add more as the system produces them on its own. However, if you wish to replenish the bacteria, you can use natural methods. For example, you can add three rotten tomatoes to your garbage disposal or flush 1/4 ounce of active yeast down the toilet every three months. While store-bought septic enzymes and chemicals are available, many additives are unnecessary and may even harm your system. The most effective way to maintain a healthy bacterial balance is to avoid using chemical drain cleaners, which can kill the beneficial bacteria in your tank.

While you can drain water softener backwash into a septic tank, doing so may cause several problems. One problem is that increased sodium chloride levels from water softener backwash can kill septic tank bacteria, decreasing the effectiveness of this wastewater treatment system. Another issue is that large calcium deposits can eventually stop up the drain field and lead to poor drainage. 

There are many potential causes of low well water pressure. The most common include sediment buildup, leaking pipes, a failing well pump, or a cracked pressure tank. 

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

If your leach field becomes clogged or saturated, it can cause several problems with your home's septic system. The clog can cause sewage to back up into your home, leading to unpleasant odors and mess. A backed-up septic system can be a health hazard, particularly if the sewage starts to leach into the ground surrounding the leach field.

There are several ways to fix a saturated drain field, including cleaning out your septic tank, adding enzymes and additives to your drain system, and installing a larger septic system.
