Note the illustration where almost twice as much water flows at 150 lbs. than 50 lbs., most of which is wasted. Moderate savings would result if your supply pressure was 65 lbs. However, even at this lower pressure, savings with a regulator would be 20%.
1 Tree size: American linden grows to 60 to 80 feet tall with a spread of one-half to two-thirds the height at a medium rate. Soil condition and fertility strongly influence height and rate of growth.  Flower and fruit: Clusters of small, fragrant, pale yellow flowers hang midway from a long, leafy bract.

Plants encountered are no taller than 20 feet--with many thin upright branches sprouting from old tree trunks, from just below the area infected by the fungus.
