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.

Stainless Steel

Replaced my seized up-rusty-iron well seal with an RPS-High quality-SS-Well Seal. My wellhead now shines like a new silver dollar.🙃👍

gary campbell (Asheville, US)

Rps was great. Wonderful customer service. Have gone above and beyond to help me

Stainless steel Well Cap

Good deal fast shipping, can't complain.

Richard Beck (Houston, US)
Excellent well seal

I am upgrading from a painted steel to a stainless steel 6 inch well seal and could not be happier with the quality of the product. You’ll pay a small premium over the standard painted steel seal but IMHO it’s worth it. It should look and perform great for years to come. RPS was invaluable and helping me to easily get the correct fitting to install into my existing configuration. My well pipe is 3/4 inch poly, my above ground pipe is 1 inch poly.

Bob Opersteny (San Antonio, US)
Quality Stainless Well Seal Kit

The 4" / 1-1/4" Stainless Well Seal assembly that I received from RPS was a high quality kit, even including 3 hose clamps. The well seal plates were high-polish Stainless, approaching the 316 L Sanitary grade 360 Grit or Electro-polish finishes that are used in FDA-Sanitary processing and Pharmaceutical industries.
Although 304 grade Stainless Steel, all pipe fittings were excellent quality and free of defects and machining/thread errors. Valerie assisted with requesting a premium shipping refund when UPS failed to deliver on time; and switched my new orders to USPS Priority Mail for better Rural shipping delivery.
Note that UPS does not deliver on weekends in many rural areas, even for 2nd day -Air premium cost!
Great Customer service to resolve my UPS delivery issue, and assistance in sizing parts/ returns.
I can recommend RPS Water Pumps to all Rural- Water Well owners who need long-lasting and rust-free water supply!
