"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!"

Septic Tanks questions, answered by experts

French drains, sump pumps, and exterior waterproofing systems are common options. Choose one that best suits your property’s needs.

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.

The dimensions of a 500-gallon concrete septic tank can vary from manufacturer to manufacturer, but the tank is large enough to handle the wastewater of a small home with up to one bedroom. Keep in mind that some states have a minimum septic tank size, and this often starts at 750 gallons. A 500-gallon septic tank may be too small to meet local regulations.

The cost of sump pump installation varies depending on factors like the type of sump pump, labor rates, and the complexity of the installation. On average, you can expect to pay around $1,200 for a standard sump pump install. However, the cost may be higher if additional features like a backup system or extensive drainage work are required.

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.
