Review on Powerful Grundfos 98562818 SCALA2 Pressure Boosting Pump: 1x115V 60Hz AVCBDF by Michael Shim

Hands down the best money I've spent. Easy installation, the only problem is finding a PEX adapter from 1 inch to 3/4 male. This thing is an animal. No pressure drop after installation. My son showered while my daughter filled the tub and ran the dishwasher. And all this at the same time without a drop in pressure. You will never know that another faucet has been opened. No bumps, instant pressure. This is the absolute best! I'm on city water and my pressure is over 33psi. This pressure dropped significantly when another faucet was opened. It made life crazy because it wasn't possible to have more than one water source at a time. Each faucet now has a constant pressure of 52psi. The only downside is that for the first time in a new house we ran out of hot water. 😂. Flow used to be so low that this was never a problem.
