To Enable Water Submetering
SINGLE POINT WATER ENTRY
Not unlike gas and electricity, water and sewer costs are being excluded from rent in growing numbers in response to America's sewer reconstricion plans, CSO (Combined Sewer Overflow).
To enable water submetering, instead of risers, supply water to each rental unit with a single point of water supply, as shown below.
VALVE, METER, THEN TEE
A shutoff valve upstream of the water meter is required just in case the meter ever requires service or replacement. Then the meter flow tube and finally one branch for the hot water tank and one for the rest of the water fed to the apartment unit, as shown below.
