"Called Trio Heating on a late Friday afternoon and they sent out two technicians (Jose & Dallin) the next morning to fix a gas heater that would not turn on. Their communication from beginning to end was great. They sent me a text 45 minutes before their arrival time and I was able to track their ETA which was extremely helpful. They explained to me what the issue was. I was able to run out and buy a new thermostat for them to install. They did a great job, cleaned everything up and put everything back together. They also typed up everything they worked on and took multiple detailed photos of the unit and emailed 10 minutes after they left. I think what they charged was extremely reasonable for the quality of work. I really appreciated not being charged a higher fee for coming out on a weekend. Will definitely use them again for my HVAC needs!"

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."

Small jobs welcome

"Home Advisor does not have the specific category for the work that was performed of replacement of graded retaining wall up my driveway and around a structure. The work utilized excavation, concrete, wood & construction. Cristian, the owner, was the epitomy of professionalism as with every crew member. Firstly, he did not try to sell me on something I did not want, much appreciated. The job was meticulously executed in record time at the price I could pay. This job has been on my bucket list for years... finally completed with a job well done!"

Septic Tanks FAQs, answered by experts

Schedule annual inspections, monitor water pressure, and address minor issues promptly to avoid major repairs.

If there’s a problem with your sewage system, you might notice water pooling on the ground around the tank, which could indicate an overflow. Clogged and sluggish drains or foul smells coming from your plumbing are also signs that there might be a blockage in your septic system.

It only takes a few days for a septic tank to fill with water after a pro has pumped it. This is completely normal, and the water is a vital part of your septic system’s wastewater treatment process. The water that fills your tank days after pumping is not the same as the tank being filled with waste. You shouldn’t have to pump your septic system more than once every three to five years unless you have a tank that’s too small for your home’s water output or there’s a problem with your leach field. 

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.

If you aren’t sure if you have a septic tank or a cesspit, you can check your property records or inspect your drainage system. A septic tank has an outlet pipe that allows liquid to drain into a soakaway or drain field, while a cesspit is a sealed tank that requires frequent emptying. If you notice a manhole cover and no nearby drainage field, it’s likely a cesspit. Signs like slow drainage or a frequent need for pumping can also provide clues. A professional inspection is the easiest way to confirm if your home runs on a septic tank or cesspit.
