There are a few recommended methods to support the drop pipe.  The first is a well seal.  This is a 
plate that fits on the top of the well casing.  It provides a seal against contamination of the well, and it 
supports the weight of the in-well assembly.  In freezing climates, the wellhead must be located in a 
heated building or in a covered well pit if no anti-freeze bleeder valve is used with the well seal. 

The other method is the use of a pitless adapter.  This is a fitting that allows your buried pipe to pass 
through the well casing underground, without the need to build a covered pit.  This system is used in 
many  conventional  well  systems  and  is  available  from  local  well  pump  suppliers.    A  well  cap  is 
needed with this method.  

The  pitless  adapter  is  ideal  for  freezing  climates.    It  also  provides  protection  against  animals, 
children, and vehicles that can damage exposed piping.   

C

AUTION

:  

The pump must be supported primarily by the drop pipe.  The rope serves as a 

safety  measure  in  case  of  pipe  breakage.    The  electrical  cable  must 

NEVER

  support  any 

weight. 

The  use  of  flexible  conduit  running  from  the  top  of  the  well  seal  or  cap  to  the  controller  is 
recommended.  This will help against contamination and damage from animals.  Please inform your 
Authorized SunRotor

®

 Dealer if the use of flexible conduit is planned, as additional parts are needed.

Polyethylene (PE) drop pipe will stretch by about 1% of its original length.  Rope will also stretch.  To 
keep it from bearing much weight, cut your rope 1% longer than the drop pipe. 

The pump cable should 

NEVER BEAR ANY WEIGHT

. Prevent this by making the length of your cable (the 

portion below the wellhead) 1.5% longer than your drop pipe.  

D

O NOT CUT IT YET

extra length is 

needed to make a slack loop at the bottom, and to make connections at the surface.  If the pump may 
need to be lowered in the future, leave some extra cable rolled up at the wellhead, so no splicing will 
be needed later.
