Commercial Water Booster Pump Installation & Service
HT Strenger designs, installs, and services commercial water booster pump systems for multi-story office buildings, apartment complexes, hotels, medical buildings, warehouses, and manufacturing facilities across Lake County and greater Chicagoland. When incoming municipal water pressure will not reliably serve every fixture in your building, a properly sized booster package solves the problem quietly, efficiently, and to code.
If tenants are complaining about weak showers on the top floor or if your fire pump is being asked to bail out domestic pressure, it is time to look at a booster.

When You Need a Booster
The village mains deliver whatever pressure they deliver. On a good day in most of Lake County that is 45 to 65 PSI at the meter. That is fine for a one-story storefront. It is not fine for:
- Three-story or taller buildings where the top floors get 20 PSI or less at the fixture.
- Buildings at the end of a long service line or on the high side of a pressure zone.
- Apartment or hotel occupancies where morning peak demand collapses the pressure across the whole building.
- Any facility that added floors, added tenants, or added irrigation without upsizing the incoming service.
- Buildings that rely on a well and cannot get consistent pressure from the well tank alone.
Variable Frequency Drive (VFD) Packages
The current standard for commercial boosters is a duplex or triplex constant-pressure package with variable frequency drives on each pump. VFDs ramp the motors up and down to hold a set pressure regardless of demand, instead of banging on and off like the old constant-speed hydro-pneumatic setups. That means less noise, less energy waste, longer motor life, and no big pressure swings when a fixture opens across the building. We install and service the major commercial brands, including Grundfos, Bell & Gossett, Armstrong, and Xylem Goulds.
Pro Tip: Ask your booster contractor whether the package includes a low-suction cutout and a properly sized bypass line. A booster that runs dry when the village drops pressure will burn a seal within minutes, and a package without a bypass loses the whole building when a pump goes down for service. Both are cheap to spec in and expensive to add later.
Sizing, Redundancy, and Code
Booster sizing is a real engineering exercise. Peak fixture load, minimum incoming pressure, target discharge pressure, and required flow all drive the pump selection and the number of pumps in the package. We size to your actual building, not to a stock catalog cut. For occupied residential and hospitality buildings we recommend duplex or triplex packages so a single pump failure never leaves tenants without water.
Service, Repair, and Retrofits
We service existing booster packages too. Common calls include leaking mechanical seals, failed pressure transducers, VFD faults, expansion tank replacement, and control panel programming. Where an older constant-speed hydro-pneumatic booster is nearing end of life, we retrofit to a modern VFD package on the same footprint and cut the operating cost noticeably.
