"Jordan was awesome! He initially sent one of his guys out to check for some gurgling and sediment in our plumbing in the basement. They took a good look and found some grading issues with our pipes. Jordan followed up with me after and then committed to coming out himself to determine options. Throughout it all he was very communicative and extremely knowledgeable. We discussed some options and moved forward with the one that made the most sense. The issue was addressed and Jordan followed up later on to make sure everything was still good. Highly recommend Jordan and team dr.drain!"

"Francisco Garcia did an excellent job finishing our basement. The work quality is excellent. The communication and flexibility throughout the project was excellent. The project finished on time within budget with zero surprises. Any concerns that arose were addressed expeditiously and professionally. I highly recommend Colorado Paradise Builders for your next project. The building inspections were coordinated by Colorado Paradise Builders and passed easily. We learned while talking to the inspectors that we had a gift by using Francisco as a general contractor. They mentioned other people in the business may not provide the level of customer service and professionalism which Colorado Paradise Builders demonstrated on our basement finishing project. I could not be more enthusiastic with a recommendation."

Septic Tanks questions, answered by experts

You can replenish good bacteria in your septic tank by adding three rotten tomatoes or 1/4 ounce of yeast every three months. Put three overripe tomatoes in the garbage disposal while running the faucet. Or pour 1/4 ounce of yeast in the toilet and flush it down. These are the best natural ways to increase bacteria in your septic tank. Septic tank additives are not necessary and may even cause harm to your septic system.

The water refills in a well through gravity that draws water from the water table to fill the vertical hole. The pump brings the fresh water through a pressure tank and to the pipes in your house. The well continues to refill indefinitely as long as you don’t use more water than the well is producing.

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.

Most septic tanks can handle two to three loads of laundry per day, or a weekly total of between seven and 10 loads. Although septic systems do require homeowners to be somewhat careful with their plumbing systems—for instance, it’s not a good idea to flush a bunch of toilet paper all at once—they can still handle fairly heavy use.

A well pressure tank can last up to 15 years. However, how long your well pressure tank lasts depends on a few factors. If you have an appropriately sized tank from a high-quality brand, it’s more likely to last longer. Maintaining clean well water also helps since there won’t be sediment mucking up the works. Keeping to a maintenance schedule ensures that you catch minor repairs before they turn into big problems that require a complete tank replacement.
