Key Takeaways:

• Pressure Drop: Every filter adds resistance. If a system is undersized, this resistance creates a noticeable drop in water pressure at the showerhead.
• Peak Flow Rate: Systems must be sized for the maximum amount of water your home uses at once (e.g., 2 showers + 1 washing machine = ~8-10 GPM).
• Valve Size: A 1-inch control valve allows significantly more water flow with less pressure loss than a standard 3/4-inch valve found on cheaper units.
• The Professional Difference: We calculate your home's fixture count to ensure your treatment system never becomes a bottleneck.

Have you ever been in a shower that turned into a trickle because someone flushed a toilet or started the washing machine? That is a flow rate issue. Installing a water treatment system can create this problem if it isn't properly engineered.

Understanding Pressure Drop (Delta P)

Think of water flowing through a pipe like cars on a highway. A water filter is like a toll booth. It slows traffic down. This resistance is measured as "Pressure Drop."

• Undersized System: Like a single toll booth lane for a 4-lane highway. Traffic backs up (pressure drops significantly).
• Properly Sized System: Like 4 open toll lanes. Traffic flows smoothly with minimal slowing.

The Critical Numbers: GPM

Gallons Per Minute (GPM) is how we measure flow.

• Standard Shower: 2.5 GPM
• Rain Shower Head: 5.0+ GPM
• Washing Machine: 3.0 GPM
• Toilet Flush: 3.0 GPM

A typical family home might have a Peak Flow Rate of 8 to 12 GPM in the morning when everyone is getting ready.

Big Box vs. Pro Grade

Many DIY softeners use restrictive internal porting or small 3/4" valves that choke flow at around 7-8 GPM. If your home tries to pull 10 GPM, you will feel a massive pressure loss.

How We Engineer for Flow

1. High-Flow Valves: We utilize 1-inch internal porting on our control valves (like the Clack WS1) which can handle flow rates up to 27 GPM—far higher than a standard home needs.
2. Media Tank Sizing: We ensure the tank is wide enough so water doesn't have to be forced through the resin too quickly, which kills pressure.
3. Plumbing Match: We match the system connections to your home's plumbing size (1" or 1.25") to prevent bottlenecks.
