Both calculators run independently β change the inputs on either side to compare results.
Plumbing
Water Pressure Drop Calculator
Calculates the residual water pressure (PSI) at the end of a piping run after accounting for elevation changes, pipe friction loss, and fittings. Use it to verify adequate pressure reaches the most remote fixture.

Plumbing
Water Meter Sizing Calculator
Determines the appropriate water meter size (in inches) for a property by comparing peak flow demand against the meter's rated capacity at the available line pressure. Use it during new construction or meter upgrade planning.
