The request
“An off-grid cabin water system: a solar pump lifts water from a hand-dug well to a cistern, and gravity feeds a sink faucet; a level controller controls the pump.”
Then tryAdd a second faucet for an outdoor sinkAdd a sediment filter before the cistern
What is in this drawing
Read the decisions behind it.
01
Represented the hand-dug well as an atmospheric tank and the solar pump as a centrifugal pump
02
Added a level control loop (LT-101/LIC-101) to protect the pump from low cistern level
03
Used a globe valve as the sink faucet with gravity-fed process line to the final consumer
Use for small-scale off-grid water supply systems where equipment and control instrumentation need to be documented without complex process piping.
