### ⭐⭐⭐⭐⭐ Makes a difference in water flow

### ⭐⭐⭐⭐⭐ Eliminated surging and reduced pump cycling
*by I***R on June 5, 2026*

This tank coupled with a new water pump (no special pump, normal on/off shurflo without variable speed) accomplished several things. Water pump cycling markedly reduced, water flow surging with low faucet flow (pump cycling on and off repeatedly) basically eliminated, smooth flow all the time. Sounds levels cut way down, not sure though how much of that is from adding this tank and how much was a combination of new pump and rerouting the water lines to eliminate right angle fittings at the pump.
