Residential and business water treatment systems. Water softeners, UV lights. We will analyze your water for contaminants such as chlorine, low pH, iron, bacteria, and devise a system to suit your needs. Treat your water from the source, as it enters your home, so whether you are drinking it, cooking with it or bathing in it, your water is pure.

"The process was quick and easy. I just provided a water sample. It was determined that I had high levels of chlorine in our drinking water. I was able to solve my water problems with only one filter. Why did I wait years to have this done? Now I can be confident that our water is safe. Highly recommended."

Additional DBAs - Roto-Rooter Group Inc, Roto-Rooter Plumbing & Drain Services. Additional address - 93788 Carlisle Ln, Coos Bay, OR 97420.

"I have never dealt with a more unprofessional business. They sent out 2 separate guys, both broke off pieces of equipment in our drain and were not able to retrieve them. We now have 3 pieces of snake in our drain and keep getting bills in the mail. I've called multiple times to try to resolve this only to be called a liar and asked how I want to pay. RotoRooter has made no attempt to fix the situation by removing the equipment from our drain, which will likely cause more problems in the future. This company has a lot of turnover and very minimal training. One of their employees recommended we call EconoRooter because they are more experienced and have better tools to complete the job. That would be my recommendation as well."

Septic Tanks questions, answered by experts

Ensuring you have adequate space for your engineered septic system is crucial. You’ll need to reserve approximately 900 square feet for a three-bedroom home’s system. However, the type of soil you have, soil absorption rate, the size of your home, climate, and local zoning code will impact the actual amount of space you need.

A septic tank needs to be pumped once every three years on average. However, every septic tank has different needs, and the proper service interval for your system may be every five years, or as frequent as an annual pump-out. Consult with your installer about the proper interval and what to expect regarding the cost of septic tank pumping.

You may want to increase the size of your leach field, for instance, if you add on to your home or install more bathrooms in your house. You can make your leach field larger by installing more pipes or expanding the area of the field itself. Improving the soil quality in the drain field can also make it more effective without increasing the area.

There are a couple of ways you can determine the depth of your well. One method is to use a device called a well sounder. This tool has a long measuring tape containing a sensor to alert you once the end reaches the water. 

Or you can DIY it by using a long tape measure with a half-filled bottle of water attached to it. Lower the tape measure into your well. Once you feel tension on the tape, you’ll know the bottle has reached your static water level. This will give you an approximate idea of your well’s depth.

The easiest thing you can do to prolong the life of your septic system is to adopt septic-safe practices. This includes not flushing non-biodegradable items, chemicals, or excessive grease down drains and scheduling regular septic tank pumping to prevent buildup. It’s also important to fix plumbing leaks promptly and to practice water conservation to avoid overloading the system. To maintain your drain field, avoid heavy vehicle traffic and plant shallow-rooted vegetation in the area. Most importantly, invest in routine inspections and maintenance to detect and address issues early.
