"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. Their work was excellent, prompt and neat. Highly recommend."

"Worst homeowner experience of my life. Hired to replace a sewer line from my house to the street - three day job turned into three weeks - said they didn’t need to shut off our water, though we asked, then broke the water line and flooded the hole, which backed up into the broken sewer line and then back into my basement - city engineers were all over the job because of safety concerns, including a teenage boy working in a 12 foot hole with no cave in support. I doubt the city of Dover would even give him a permit again. - never worked a full day. Left early for reasons ranging from broken equipment, teaching karate lessons, or going to daughter’s events - hole was definitely not packed back in correctly as we ended up with a moat the following spring. A pizza delivery guy literally fell into the dent in my front yard. - cost of job went up 150% from original quote and he wouldn’t itemize the bill - and here we are a year and a week later and my sewer line is backed up again so the job was bunk. I’m not even kind of surprised. Dana is the worst. Stay away from this business. I will be filing complaints with anyone and everyone who monitors these types of business. Horrible."

Septic Tanks questions, answered by experts

While you can drain water softener backwash into a septic tank, doing so may cause several problems. One problem is that increased sodium chloride levels from water softener backwash can kill septic tank bacteria, decreasing the effectiveness of this wastewater treatment system. Another issue is that large calcium deposits can eventually stop up the drain field and lead to poor drainage. 

A well pressure tank is located between the well and the well pump, and it stores your water under pressure so that the well pump can eventually do its job. The well pump is activated whenever you turn a faucet on—it pulls the water from the tank into your home. Both are vital parts of a complete well water system.

Anaerobic septic tanks are the most cost-effective type of septic system, with an average cost of $3,000 to $8,000. Sand filter septic systems are the next most affordable, ranging from $7,000 to $18,000. Mound systems have the highest price tags of the bunch, coming in at $10,000 to $20,000 per installation.

If you notice that your well pump runs continuously, it’s important to take action quickly to avoid further damage. A few common issues may be to blame for a continuously running well pump, such as mechanical damage, a faulty pressure control switch, low water level, prime loss, and leaking pipes and fixtures.

With regular servicing, a well pump usually lasts between eight and 15 years. Variables include level of usage, frequency of servicing, and pump quality. You may also be able to hire a local well pump repair service to fix your pump rather than replace it. 

However, often the cost to fix significant problems is as much as or greater than replacing the damaged pump with a new one.
