"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 FAQs, answered by experts

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.

Over time, your septic tank can accumulate a buildup of sludge at the bottom of the tank. If left unpumped and uncleaned, the sludge will back up into your pipes and home, causing failure and extensive (and smelly) damage. Repairs to your septic system can be costly, which is why regular maintenance is required. It takes about 30 minutes to pump a septic tank that’s 1,250 gallons or less or 1 hour for larger varieties.

Septic tank lids may or may not be buried in a yard. Most lids are buried at least 4 inches deep unless you have an aerobic septic system. Aerobic septic systems need frequent cleanings, about every four months, so it’s best to leave these lids aboveground for easier access. For buried lids, homeowners can use risers that make it easier to locate and access a buried septic tank lid.

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.

Depending on the size and location of your septic tank repair job, you may want to let the septic pros finish before tackling other backyard work. However, in some cases, it’s not a bad idea to coordinate between your providers if the timing’s right and your septic repair pro says it’s safe to do so. For instance, if the septic repair work is happening in the fall, you might want to take advantage of the opportunity to prepare your backyard landscaping for winter , or in spring, start mulching the garden beds.
