This easy-to-install pressure switch helps regulate water flow by controlling when your pump turns on and off. It maintains consistent water pressure for household, irrigation hose, and other water systems. Suitable for both 110/115V and 220/230V well pumps, it can handle motors up to 2HP, depending on voltage.

Ideal for homeowners, DIYers, and professionals maintaining water access systems, this pressure switch works by reacting to pressure changes in the system—activating the pump when pressure drops, and turning it off once the target pressure is restored.

It's also a practical replacement for worn or outdated well pump switches in residential well systems.

Adjustable Settings for Pressure Tank Compatibility

Pre-set to 20/40 psi, this well pressure switch allows users to easily adjust the pressure differential to match their system's needs—commonly 30/50 or 40/60 psi—making it ideal for systems using a pressure tank. This flexibility supports better control and balance across different plumbing layouts.

For users replacing an older control switch, 40/60 psi remains one of the most popular residential settings for consistent operation.

The well pressure switch is enclosed in a durable cover to protect internal components and ensure reliable long-term performance. A pressure gauge can also be used alongside this switch to monitor system performance and assist with diagnostics.

Our Pledges to You

  1. Be a company our Grandfathers would have trusted. The trend of ‘outsourcing’ customer support after the sale is a trend we wholeheartedly oppose. We are an American, family run company and our USA engineers support you before and after the sale.
  2. No sales pressure. Ever. Nobody in the company is paid on commission. We think this is important. Their role is to make sure they find the right pump for you and your well. If we don’t have a livestock solar pump that will suit your needs, we will help you find a solution elsewhere. Our job is to help get you water.
  3. Reliable Water. All manufactured products have occasional issues and we can’t claim to be perfect. However, we are proud of a near perfect track record in getting our customers water. This starts with selling a pump sized for your usage with our Water Assurance Plan and promptly addressing warranty issues to get you up and pumping again quickly.
  4. Give you the power! When you control your ability to pump water out of the ground, whether that is in the field or at home, it makes you more resilient and independent. We are here to help educate you about solar water pumping for livestock and our systems over the phone, with our manual - so you can install yourself. Take control of your water supply today.
  5. Fight for the American rancher. RPS is a David & Goliath story of a small American company fighting against a big European pump corporation that cares more about profits then the longevity of their pumps and the sky-high price for ranchers. Thanks to all our customers for the support of small business vs. foreign corporations trying to profit off some of the hardest working people in our great nation.
