Submersible Well Pump Drop Pipe Kit for Quick and Easy Installation

Short on time, in a remote location, or simply want to avoid running to multiple stores? The One-and-Done Kit provides everything needed to install a submersible deep well pump, making it the hassle-free solution for DIYers. That’s why we call it “One-and-Done.” One click, and you’re ready to install your new pump.

This kit is perfect for homeowners, rural landowners, and prepping for long-term water supply reliability in remote or drought-prone areas. Every item is selected for its reliability and compatibility with deep well pump systems, helping you install the right solution the first time.

How to Choose the Right Setup

Step 1: Choose the Desired Length

Select from 50, 100, 150, 200, 250, or 300-foot poly pipe kits (wire, pipe, and rope are matched to chosen depth).

Step 2: Select your pipe diameter

Determine whether you need a 1” poly pipe (up to 15 GPM) or a 1.25” poly pipe (15-25 GPM).

If you are unsure, contact our team and we will help you determine the best pipe diameter based on your total well depth and pump needs, especially important in deep well applications where friction loss matters.

Step 3: Choose your plumbing option

Choose between a Well Seal Assembly or a Well Cap with Pitless Adapter.

Match the well casing size (4”, 5”, 6”, or 8”) to ensure a secure seal and freeze-proof setup.

Compatible with RPS AC Deep Well Pumps

We recommend the 1” well pump installation kit for our 05RPS, 07RPS, and 10RPS series submersible pumps delivering 5-15 GPM. For higher flow rates, 1.25” kits work best for 13RPS, 18RPS, and 25RPS models (15-25 GPM).

These kits account for necessary plumbing reductions as needed. No need to add extra fittings or worry whether everything will match.

Info On Well Seals

• Auxiliary hole for wiring
• Rubber gasket expands for a tight fit
• Compatible with 1” to 1.25” drop pipe

Well Seal Sizing Specs:

• 4” Well Seal:
• 1.25” main through-hole
• ¾” NPT auxiliary conduit hole
• ½” NPT vent port
• 5”, 6”, and 8” Well Seals:
• 1.25” main through-hole
• 1” NPT auxiliary conduit hole
• ½” NPT vent port

Note: The actual diameter of the 1.25” drop pipe hole is 1.70”. Use reducing couplers when using a 1” drop pipe.

Note on Varying Well Casing Sizes for Well Seals 

Well casing measurements can vary slightly depending on various factors such as pipe material, drilling process, casing age, and local installation standards. This is common across 4”, 5”, 6”, and 8” well casing sizes.

For example, a 2-year-old 6" well in Indiana may not have the exact same measurements as a 6" 65-year-old well in Texas. Not to worry! The black gasket around the bottom of RPS stainless steel well seals will swell with exposure to water to help seal off slight inconsistencies in measurements. 

In rare cases, you can also add some foam tape around the gasket for a more exact fit on wells with "unique" measurements. And as long as the lip of the well seal is sitting over the well casing, your well pump will be safely supported.

Built for Reliable Clean Water Access

Every pipe and fitting in this kit is rated for clean water applications, with materials chosen to minimize corrosion, debris buildup, and seal degradation. All poly pipe included is designed for longevity in cold environments and can withstand long-term outdoor exposure.

The components are engineered specifically for deep well setups, prioritizing water safety and reduced maintenance.

This isn’t just a random stock of parts. It’s a complete plumbing set, with products matched and tested for real-world pumping conditions, whether you are working with PVC casing or switching from an older steel system.
