💡 What piping alignment tricks keep a pendent fire sprinkler head handy during garage conversions?
A dead-simple threading swap usually kicks the project forward without borrowing specialty gear.
- Align the drop threads straight so the torque wrench bites tight without stripping the barrel
- Leave the factory glass bulb exposed to air currents so heat transfer stays fast when smoke rolls
- Hit the pressure gauge once before sealing drywall so the circuit stays rock solid
