How we got these numbers
National benchmark costs from RSMeans, Angi, Fixr, and HomeGuide are adjusted for Missouri using two federal datasets: the Bureau of Economic Analysis Regional Price Parity (RPP) index and the Bureau of Labor Statistics (BLS) Occupational Employment and Wage Statistics. Missouri's RPP is 0.9 (national baseline = 100) and its BLS labor adjustment factor is 0.91. Higher RPP means goods and services cost more relative to the national average; the BLS factor scales contractor labor rates to local wage levels. We blend these two adjustments, weighted 40% RPP, 60% BLS labor, to produce the ranges shown above.
adjusted_cost = national_benchmark × (0.4 × RPP/100 + 0.6 × bls_labor_adj)
RPP(Missouri) = 0.9 · BLS adj = 0.91

Build sequence
- 1
Unplug the old pump, disconnect the discharge, and lift it out.
- 2
Set the new pump level in the pit on a stable base.
COMMON MISTAKE
A pump tilted or resting on silt clogs and fails early.
- 3
Connect the discharge pipe with a check valve to stop backflow.
COMMON MISTAKE
Skipping the check valve lets water run back and short-cycle the pump.
- 4
Set the float so the pump turns on and off at the right levels.
- 5
Test by filling the pit, confirm it drains, and add a battery backup if desired.
