Another thought. Go buy them low pressure nozzles. One could outfit several average departments for the cost of one fire pump.

I'd like to think the fire service would simply use their on board pump and boost the FDC when and if they need that extra 20 or 30 psi, instead of adding that cost to every building. My justification is that for 99% of the responses, 100psi is sufficient and the 1% is costing between $100,000 and $200,000 per building to accommodate.
