How to cut the cost
- Set the boost pressure no higher than needed (around 50-60 psi).
- Use a variable-speed model that ramps down for small flows.
- Fix leaks; a constant drip can trigger frequent short starts.
Cheaper ways to get the job done
Matches motor speed to demand, often using 30-50% less than on/off pumps.
