No trying to talk me into any other services I didn't need, no bs, just straight up honest work. Will definitely hire again when the time comes."

"Somehow rain water was flooding into my septic tank causing it to backup into the house - yuck!  Jim came out after 9:30 p.m. on a Sunday to rod the sewer out to the septic tank and scheduled a day to come out the following week to inspect and replace the main sewer line if needed (they were working a major construction job and that was the earliest that he was available).
The following Saturday when the forecast called for heavy rains late afternoon - Jim called me and came out with another plumber and apprentice to dig up and replace the main sewer line in advance of  the heavy rainfall.  
Needless to say, it worked and there was no flooding at all during the rainstorm - we even flushed toilets and my daughter took a shower, but no backup and all the drains worked flawlessly!"

"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

Septic Tanks FAQs, answered by experts

The size of your water well pressure tank is limited only by your budget and the amount of space you have to use. Larger tanks can hold more water, meaning your well pump will need to cycle less often. This can extend the life of both the pressure tank and your well pump. Larger tanks cost more and take up more room, though.

A septic tank riser features a base ring that you need to install flush to the opening of the septic tank. After thoroughly cleaning the opening of the tank, fit the base ring over the opening and use a butyl sealant rope to create an airtight seal with the tank’s rim. Cut the riser rings to the appropriate height and stack them on the base ring. Then, install the riser lid. This task might be taken on by an experienced DIYer, but you should always call a septic tank professional if you are unsure of your skills.

The depth of your septic tank has nothing to do with its size. In fact, some septic tanks can even be installed above-ground! Like other sizes, a 1,000-gallon septic tank could be buried as shallow as 4 inches below the ground or as deep as 4 feet. It all depends on your specific property.

Wells typically replenish at a rate of about five gallons per minute, but several variables can influence how quickly they refill. A deep well will take more time to replenish than a shallow one. The replenishment rate can be slowed by issues such as leaks, damage, a faulty well pump, or a clogged well screen. Other factors, such as the surrounding geology, regular precipitation, and proper maintenance, also affect the recovery rate.

When considering the price of drilling a well, factor in how much you’ll save in water costs per year. The average family of four uses 100 gallons of water per person per day in the U.S. With a private water well, you can save hundreds each year.

Wells are also environmentally friendly. You don’t need to worry about drinking water treated with chemicals. Talk to at least three well pump contractors in your area. They’ll be able to tell you more about your options, give you different quotes, and discuss the biggest concerns.
