"The septic tank had been incorrectly vented in a manner that made it dangerous so they replaced the cap and made it easier to access in the future. Everything was explained to me and the service men were professional and pleasant."

"I thought they did a great job; they were very professional and courteous, if there was anything I did not like was that the initial job was to unclog the main sewer line, but could not do it, they still charged me $275, in the past I only paid from $75 - $150 when they unclogged the line, they charged so much money for not unclogging, I think they should have bypast that charge, I did pay $9500, to replace the main sewer line and trap, which I'm ok with."

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 typically lasts between 5 and 15 years. However, its lifespan can be influenced by several factors. High-quality, appropriately sized tanks tend to last longer, with some top-of-the-line models lasting up to 30 years. Regular annual maintenance, including inspections, cleaning, and prompt repairs, is crucial for extending the tank's life. Water quality also plays a significant role; water with high levels of sediment, minerals, or rocks can cause premature wear. Overworking an undersized tank can also limit its lifespan.

Good news: You’ll naturally increase the bacteria in your septic tank simply by using it. If you want to encourage more good bacteria growth, stop using products and household cleaners that kill bacteria, such as bleach and harsh chemicals. Never flush antibiotics, and make sure only water and waste go down the tube—not paper products, feminine hygiene products, or diapers.

The physical constraints of hand-drilling a well limit the depth you can achieve. Manually digging with picks and shovels may only lead to shallow wells of up to 60 feet in depth. To reach greater depths, you need more specialized equipment. The diameter of your well and the tools you’re using will determine how far down you can dig.

You can add three rotten tomatoes or 1/4 ounce of yeast to your septic tank to speed up the decomposition of sludge. You can add the tomatoes by way of your garbage disposal and the yeast by way of your toilet. You can do either of these additives once every three months as needed.
