They respond quickly, are very skilled in what they do, very professional, and very fair in pricing their services. I have used them for commercial and residential services for the last seven years."

"Pure Home Remodeling was recommended to us by a colleague for our kitchen and 2 bathrooms remodeling project and we are very thankful for that recommendation. Our Project Manager was really easy to work with and extremely easy-going with us. We really valued how experienced Our Project Manager is when it comes to all the tasks that were involved in the remodeling including where to shop for things such as tiles, vanities, faucets, light fixtures and how all the workers were willing to give their feedback in order to help us make the best decision for our house and budget. During our remodeling, Our Project Manager gave us daily updates in regards to the progress and he even visited our house daily and even helped us with a non-related plumbing problem (a broken pipe that leaked into the wall of our laundry area). Our Project Manager and his crew demolished our kitchen and bathrooms completely and turned it into our favorite spaces in the house. We highly recommend working with Our Project Manager at Pure Home Remodeling for any type of remodeling project."

"I had a problem at my vacation rental. John contacted me quickly when I posted my problem for quotes online. I had a failing septic. It was no longer draining. John came out and accessed the the situation and based on faulty drawings I supplied, he gave me an estimate for repair. I agreed to the figure. When he discovered that the drawings were wrong and he only had to dig up 5 feet (not 14) between the septic tank and the seep box he lowered his estimate. You can't ask for more honesty and fairness. He and his worker completed the job in less than 2 days. Hire him!"

"The technician emptied the freezer, which was in the basement, to work on the part that needed repair. Then he neglected to put anything back into the freezer, including a turkey I had bought for Christmas and a rack of ribs. Two days after he left, I went out of town for two weeks. The turkey actually exploded and spewed its liquid all over everything, which had to be discarded. I let AHS know and they couldn't even bother to call me or follow up on this. I'm considering not renewing my contract with them because of the quality (or lack thereof) of many of the providers they send."

Septic Tanks FAQs, answered by experts

Yes, it is generally okay to oversize a well pressure tank, and it will not harm your well system. The primary advantage is that a larger tank reduces frequent pump cycling, leading to longer, slower cycles with fewer startups. This can result in less wear and tear, potentially increasing the lifespan of the pump and conserving energy. However, there are drawbacks to consider. Oversized tanks have a higher upfront cost and require more physical space. While not necessarily a bad thing, opting for a tank that is appropriately sized for your well is often the most efficient choice in terms of cost and space.

Septic tanks and cesspits are both types of sewage and wastewater systems, but they differ in key ways. The main difference between the two systems is that septic tanks separate sewage from wastewater and allow the latter to flow into a drainage field to filter and disperse into the soil. Cesspits don’t have outlets and instead, store sewage until it needs to be pumped by a professional.

Wells should be at least 100 feet deep for drinking water, but they may need to be deeper depending on the local geology, water quality, and your household’s water usage. Work with a qualified well drilling professional who can assess the appropriate depth for your well and test the water before drinking it.

The average cost to replace a septic tank or install a new system is typically around $7,350, with a broader average range of $5,000 to $12,000. However, total project costs can vary widely, from $5,000 to as much as $22,500. Key factors influencing the price include the size and type of the septic system, the tank material, and the size of your house.

It's important to distinguish between the cost of the tank itself and the cost of the entire system installation, which is significantly more. For the tank alone, costs vary by size:

  • A tank for a one-bedroom house typically costs $500 to $900.

  • A 1,000-gallon tank, suitable for most one- to three-bedroom homes, costs between $900 and $1,500.

  • A tank for a five- or six-bedroom home generally costs $1,200 to $1,600.

With regular testing, treatment, and maintenance, water from a community well should be safe to drink. Unfortunately, the EPA does not regulate private wells, and contamination can happen. 

If you have doubts about the quality and safety of your drinking water, you have options for testing. You can pick up kits from your local home supply store or harvest samples and send them to a local testing facility. To get the most complete water quality testing and system diagnosis, seek a local well professional. They know what to test for and can recommend and implement a longer-lasting solution.
