Make Your Own PVC Water Well Hand Pump

PVC Water Well Hand Pump

Below is a 9 part video series by youtuber MeAndMother2 on how to make a PVC water well hand pump. Below I listed the links he gave on the schematic diagram and a printable parts list, and links to where he got some of the parts. 

 

Parts List for Hand Pump for Water Well Using PVC Pipe and Fittings

This goes with the Schematic Diagram 

 

A – 1 inch PVC Schedule 40 pipe

B – 3/4 inch PVC Schedule 40 pipe

C – 1 1/4 inch PVC Schedule 40 pipe

D – 1 inch cap

E – 1 1/4 X 3/4 Sch. 80 adapter

F – 1 1/4 inch coupling, collar, Sch. 40

G – 3/4 inch, slip glue joint to external thread, Sch. 40

H – 3/4 inch, slip glue joint to internal thread, Sch. 40

I – 3/4 X 3/8 bushing adapter, Sch. 80

J – 3/4 inch diameter Stainless Steel ball, type 316, grade 100

K – 5/32 or 3/16 diameter PVC welding rod glued in as a ball retainer 

Buy the Schedule 80, 3/4 X 3/8 bushing adapter before the balls because there are differences between manufacturers of pvc plumbing parts.  The part that I used has an opening of 11/16 inch where the ball sits.  The ball must seal but also release easily with no sticking.  If the opening is too large the ball will bind.  Measure the ball seat opening in the bushing that you find. Do not use a larger ball than 3/4 inch diameter in a 1 inch pvc schedule 40 pipe.  The balls will need a retainer that allows only about 3/4 inch movement.  With the retainer the balls will stay close to the seat and will make faster valve action.  Look for the stainless steel balls on Ebay or go to www.precisionballs.com . PVC welding rod can be found at www.usplastic.com.  Printable parts list here.
