Assembly Procedure For Pitless Adapter System
(The following instructions are very detailed, and should tell you everything you need to know.
If you have questions, please phone 775-265-1220.)
For using the Simple Pump with its own pitless exiting into an underground pipe.
The Simple Pump Pitless Adapter is designed to deliver water through a below-ground special fitting. Using this system directs water through the pitless adapter and will not allow water to be delivered through the above-ground pump head.
The Simple Pump Pitless has two parts.
A “saddle” portion is affixed through and to the inside wall of the casing having a compressive seal drawn tight against the inside wall of the casing by a large nut. The “rider” portion of the pitless holds the weight of the pipe and water by sitting in the saddle against an o-ring seal.
The system is designed to accommodate a modified Merrill 50 pitless adapter installed between 48” and 84” below the top of the well casing and below ground. The modified pitless adapter provided, is designed to be installed in a 6” or 8” well casing through a 1 3/4” hole in the casing wall.
The 7/8″ bore, through the Merill 50 pitless along with the application of a rod gland with u-cup seal and stainless rod, allows the water to be contained within the piping while the pumping energy can pass through the pitless.
A spring-to-close check valve is required on the buried line between the Simple Pump pitless adaptor and the tee connecting into the buried line that runs between the well head and the pressure tank.
When the submersible is running, the water must be directed to the pressure tank rather than back-feeding the Simple Pump. The check valve prevents this from happening.
A spring-to-close check valve is also required on the buried line between the submersible pump pitless adaptor and the tee connecting into the buried line that runs between the well head and the pressure tank.
When the Simple Pump is running, the water must be directed to the pressure tank rather than back-feeding the submersible pump. The check valve prevents this from happening.
Please do not attempt this installation unless you are familiar with pitless adapters and how to properly install them.
Inexperience can easily result in dropping components to the bottom of the well. When installing the system, the work is best performed by two persons capable of handling perhaps 75 pounds each. Make sure you are very familiar with each step before you start it. If you are uncertain about any of these procedures, please call for help before you begin.
The pitless adaptor is comprised of a 17″ long PVC adaptor, Merrill 50 pitless modified by Simple Pump, a nylon6 rod gland, a 5/8″ stainless rod and a 72″ long piece of 1/2″ allthread. All rods are stainless steel. The 5/8″ stainless rod as part of the pitless has a u-cup seal in the rod gland.
