"My elderly mother is partially blind and disabled. On November 1, 2021 her washing machine broke leaking water in her home. In desperation she called rotor rooter. Roto rooter came out, stopped the leak, and put dryers in and left. They returned a few days later to remove the dryers. The technician quoted my mother a cost of about $3000.00. My mother signed a contract but could not see what she was signing. After Roto rooter Reno removed the dryers they sent a bill to my mother for $9000.00. The contract she signed stated Roto rooter would remove walls, roofing, insulation, baseboard, tile etc. Roto rooter didn’t do any of those things. Roto rooter is price gauging and took advantage of an elderly disabled woman. Roto rooter technicians were in the home no more than 3 hours total. First my mother did not have capacity to enter into a contract as she couldn’t see what she was signing. 2 Roto rooters technicians told her the cost would be about $3000.00. 3 Roto rooter did not do the work in the contract. I believe Roto rooter is commuting elder abuse and fraud."

A-Plus Water Services, Inc., a local, family owned and operated business serving Snohomish, South Skagit, North King Counties and Camano Island areas since 1991. Over the past 20 years, we've seen a number of competitors enter the marketplace. Some are gone and a few are still around. What's the secret to our success and longevity? It's no secret. We treat our customers the way we would like to be treated. We use first rate materials, do a thorough job and clean up behind us. A new well pump should last 10 years or more and we do our best to see that it does. Quality doesn't have to cost more. Service companies are only as good as their employees. Sales and service people come and go. We are family owned and family run. When you call you get prompt, courteous service from someone who has been here for years and will continue to be here for years to come. Someone who cares, and knows that taking care of customers is what it is all about.(PLEASE NOTE WE ARE NOT WELL DRILERS)

"These guys are the best in the business! They have the absolute best prices and the most knowledge you’ll ever find. They showed up on time they communicated clearly and most of all they were unbelievably fast. Do not hesitate to contact them for anything well or pump related. Friendly, knowledgeable, quality work done at a very good price. "

"Do not hire. They will take advantage of you. We had them out to pump our septic system. They told us our drain field needed a jet-vac treatment (quoted at $3600) and possibly a new pump (quoted at $5000). They filed a report with the county saying that our pump was deficient and we got a letter in the mail saying that we had to take care of it. Those prices seemed really expensive to me so I called around. Multiple other septic companies told me not to hire Septic Solutions as they had often get calls like this from customers questioning prices and if the recommended services are really needed. I had { remove company name} Septic come out for an inspection instead. { remove company name} said that everything was working perfectly and if the jet-vac and pump were needed { remove company name} would charge 5000 total. I had to pay for an extra inspection to get things cleared with the county. Do not hire Septic Solutions. They were not honest and preyed on my lack of septic knowledge. I will be using { remove company name} Septic in the future."

Septic Tanks questions, answered by experts

How to size a well pressure tank is determined by three factors: flow rate, or how many gallons per minute your well pump produces; minimum runtime; and pressure switch setting. Most pressure tanks have a pressure switch operating at 20/40, 30/50, and 40/60—the first number is the pressure needed for the pump to turn on, and the second number is the pressure needed for the pump to switch off. Most homeowners relying on well water require a water pressure tank ranging from 20 to 80 gallons. 

To determine the right size for your submersible well pump, find your well depth, water demand, and well casing diameter. The pump should match your well's specifications and meet or exceed your drawdown and pressure requirements. 

For precise sizing, make sure to research the different well pump sizes, consult the manufacturer's recommendations, or seek guidance from a professional well pump installer.

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.

Many septic professionals agree that spring is the best time of year to empty a septic tank. By this point, the temperatures have usually warmed up enough so that the ground is no longer frozen, which makes it easier to access the tank (and less likely for the waste to be frozen inside the tank). Summer and fall are also decent times to do it, but winter isn’t.

Baking soda does very little to nothing for a septic tank, but it can help unclog a drain or clean out a garbage disposal. Rotten tomatoes and yeast are the best ways to increase the bacteria in your septic tank naturally. You can add these to your system once every three months.
