"Replaced leech field- he did an excellent job removing my old leech field and replacing it with a better system. From the time I entered the job in homeadvisor (approx 8am) I was called back before noon. We scheduled a site review later that day. From the time I selected Roadway, there was constant progress. Even when the permits were in progress, they were in constant contact to let me know what was going on. When the permits were in order, they worked nonstop until the job was done.

Septic Tanks questions, answered by experts

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. 

There are three layers of wastewater in a septic tank: scum (solid waste that floats to the top of the wastewater), liquid (the relatively clean liquid wastewater in between the two other layers), and sludge (solid waste that falls to the bottom of the wastewater). The buildup of sludge is one of the main reasons septic tanks need to be pumped. If the tank is more than 1/3 of the way full with a combination of sludge and scum, it’s time to call a pro for pumping.

A septic tank should be emptied approximately once every three to five years, though this frequency will vary depending on your water usage, the size of your tank, how many people are in your home, and other factors. A maintenance plan for your septic system may be useful for professional emptying and inspection of other important parts.

A mound septic system, when properly maintained, can last between 20 and 25 years on average—though some last longer or malfunction sooner than that. The most important part of maintenance is getting an annual inspection of the vital parts of the system to ensure they’re in proper working order and not too backed up with sewage.

If your well water supply suddenly runs dry, it could be due to a faulty pressure switch. A bad pressure switch can affect the pump's operation, leading to a loss of water. Testing the switch to see if it functions correctly is the first step in resolving the issue and restoring your water supply.

If the switch is faulty, it may need to be repaired or replaced. If the issue is more complex and involves other components, consult a professional well technician so they can address the issue and fix the water supply.
