    • 1). Install a nipple on the hot water outlet of the primary water heater and tighten with an adjustable wrench. Fix a ball-valve on the nipple. Wrap Teflon tape at least twice around all the connecting ends of the pipe fittings.

    • 2). Install a nipple on the hot water outlet of the primary water heater and tighten with an adjustable wrench. Fix a ball-valve on the nipple. Wrap Teflon tape at least twice around all the connecting ends of the pipe fittings.

    • 3). Install a union on the other opening of the nipple connected to the pressure reduction valve. Fix another nipple on the union. Unscrew the union into two halves: one half fixed to the pressure reduction valve and the other free with the nipple attached to it.

    • 4). Fit a tee on the booster inlet opening by a nipple. Out of the three openings in the tee, the opening perpendicular to the other two openings should be fixed to the nipple joined to the booster.

    • 5). Fix the free half of the union to the left opening of the tee. Bring both the halves of the union close enough to be joined together by moving the booster. Connect the halves with the wrench.

    • 6). Fit a drain valve on the third opening of the tee with the wrench.

    • 7). Connect a union to the booster outlet opening through a nipple. Use another nipple to connect a temperature and pressure gauge with the union.

    • 8). Fit a nipple to the other opening of the gauge. Connect a shock absorber to the other end of the nipple.

    • 9). Make the final duct for the outlet by connecting a nipple to the shock absorber. Join the nipple with the dish water inlet opening through a flexible pipe of appropriate length.
