💡 Where should plumbers mount a hydronic booster unit for reliable home heat?
Proper alignment prevents premature wear on spinning internals and saves big cash.
- Mount the unit on the cold return line so lower temps protect plastic seals
- Align the shaft horizontal so floating air bubbles travel straight to the vent
- Thread bypass pipes nearby so excess pressure never blows fragile pipe joints
- Add manual isolation valves so shutting water off stays super handy later
