About PlumberCalc
Just finished putting together PlumberCalc.com with 22 different calculators I've been working on. Got tired of bouncing between different apps and websites every time I needed to do basic plumbing calculations.
Covers the stuff I find myself calculating regularly:
- Pipe sizing and flow calculations - get the right pipe diameter fast
- Pressure loss calculations - figure out system pressure drops
- Drain and vent sizing - proper drainage system design
- Water heater and expansion tank sizing - residential and commercial
- Pump sizing and selection - match pumps to system requirements
- Hydraulic calculations - flow rates, velocities, head loss
