"Excellent work by Alex of Mr Rooter! Our water heater stopped working and Mr Rooter arrived same day. Alex reviewed and diagnosed the problem. The pilot needed attention and restarting, plus the Bleeder Tank and Release Valve required replacement. All done quickly, professionally and with clarity in explanation. I would recommend Mr Rooter"

"I had to pay an $85 service call fee (on top of monthly Choice Home Warranty subscription) to have a guy literally look at the outside of the tank and tell me it was just the burner."

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks FAQs, answered by experts

Deciding between an engineered septic system and a conventional one depends on property size, soil quality, local regulations, and environmental factors. If your property has limited space, poor soil, or is close to sensitive environmental features, an engineered system may be required. Professional site evaluations, considering water usage, long-term plans, and budget constraints, can help determine the appropriate choice. Consulting with a septic system professional is crucial for ensuring compliance with regulations and selecting the best system for your property's unique needs.

Since vinegar is a weak acid with a pH of two to three, it’s generally safe for septic systems. It won’t eat away at the good bacteria in your septic tank and can help break down the sludge, which is its bottom layer. However, like with everything in life, moderation is key.

Several signs can indicate a faulty well pump pressure switch. These include your pump running continuously, the pump not turning on at all, or a sudden and complete loss of water. Other symptoms are weak water pressure or an erratic, unpredictable water flow from your fixtures. If you notice these issues, the pressure switch may be the cause. Testing the switch can help diagnose the problem. A faulty switch will likely need to be repaired or replaced. If the issue is more complex, it's best to consult a professional well technician to ensure your water supply is restored correctly.

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.

A gurgling toilet usually doesn’t mean that your septic tank is full. If waste can’t drain into a full septic tank, you’ll see water and sewage backing up into your fixtures, but the air that causes gurgling is a result of poor venting. You are more likely to have a clog in your vent stack or a damaged air admittance valve.
