"Larry called right back and scheduled appointment over the weekend. He arrived on time and called ahead as promised. He was very transparent in his hourly pricing up front. Upon arrival he got right to the job and moved quickly to remedy the situation. While the job was less straightforward than I thought, It was clear he wasn't trying to run the clock out. He solved the problem swiftly with expertise. His work was very well done and clean. He didn't try to upsell me at every turn as I've experienced with other plumbers. I would definitely hire him again to handle repairs and larger jobs."

"It was great luck that Jason of J Drains was working on a job near my home and was able to come by after he finished that job to check my hot water heater. He fixed it right away because he spotted what was wrong quickly. Jason was very professional and polite. I recommend this company!"

"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 company called us the day after the earthquake, offering to come and do a free check in the crawlspace to be sure there is no damage or places needing repair in the liner after the quake. I phoned them yesterday to make the appointment and they came out today. And there is no damage or repairs needed, and the liner held up, still attached to the foundation cement stones and pillars. I felt this was very thoughtful of them to remember us. Since we installed the product a year ago, they have helped us feel comfortable that the product is doing what it is supposed to do. They also came out during the rains (however brief) in late February and checked that everything was still dry (not that we had flooding or ground water tables rise, but we were concerned that rain might have been coming in from the side vents in the house siding to the crawlspace). It was dry and everything looked good, so we determined that no more work was necessary to close up the house's side vents. That was money and time saved. ...Professional company and good people.

"AHS is ok. They cover repairs of most everything under the roof of your house. The companies that contract with them are not always the best. You call AHS with the issue, they send a fax to the repair company and give you the contact info. If they don't contact you within 24 hours, you call them. Sometimes they answer, sometimes they don't. When they arrive (usually three days or so later), they service the item. if it has issues within the 90 days, you call AHS again, they are sent out with no charge. If the serviceman decides the unit is unrepairable, AHS will allow you to choose a replacement from their listing (usually not as good as what you have) they will install and remove your old item, or give you wholesale amount to buy and install your own. Prices vary on what you want covered and what you want the copay to be, plus where you live. For me it is 49.99 per month with a 75.00 time of service order. You can have more than one item serviced at the same time under the same fee. If you have a SEAR product the repair guys are great. Not that wild about the other ones they send out. But it is a big savings compared to calling someone on your own. The cost of service is only the 75.00 copay."

Wells and Pumps questions, answered by experts

No, a larger well pressure tank will not increase your home's water pressure by itself. Water pressure is determined by the pressure control switch on the well pump.

However, a larger tank does offer other benefits. It can store more water, which allows you to run water for longer periods before the pump needs to turn on. This reduces how often the pump cycles on and off, leading to less wear and tear on the pump and the entire well system. Consequently, a larger tank can help extend the life of your equipment and may prevent future pump issues that could affect water pressure.

If your goal is to increase water pressure, consider these alternatives:

  • Adjust the pressure settings on your tank to a higher PSI (pounds per square inch).

  • Replace your current pump with a model that has a higher flow rate, measured in gallons per minute (GPM).

  • Have a professional install a water pressure booster pump in your plumbing system.

  • If you experience pressure fluctuations, consider upgrading to a constant pressure system.

How do you set your well’s pressure tank? All you need to do is first drain the tank of water and find the pressure switch. Remove the switch cover and adjust the switch with a wrench—clockwise to increase water pressure, and counter-clockwise to reduce it. Each complete turn of the nut on the switch should equal 2.5 psi. Once this is done, replace the switch cover. All that’s left is to adjust the pressure of the tank itself using an air compressor and a tire gauge to support the new setting.

The Centers for Disease Control and Prevention (CDC) recommends testing your well at least once a year to check for bacteria and contaminants. If you live in an area prone to flooding, runoff, or any other environmental concerns, it can be a good idea to check two to three times per year.

Several warning signs can indicate current or future issues with your well pressure tank. If you notice inconsistent water pressure, water spitting from your faucets, clicking sounds, or electricity bill spikes without other obvious causes, it may be time to get your pressure tank and well system looked at by a professional.

The disadvantages of having a well include more maintenance, like annual testing and inspections, and high up-front costs to drill a well. Well water is also vulnerable to contamination, which is why keeping up with testing is important if you own a well. When it comes to well water versus city water, well water does offer more independence and is a reliable water source.
