All olive compression fittings must use brass or copper olives. Use thread sealing tape or approved thread sealant on all fittings. - Page 24 Damaged valves must be replaced. PIPE SIZES The cold water pipe to the water heater should be the same size or bigger than the hot water line from the water heater. The pipe sizing for hot water supply systems should be carried out by persons competent to do so, choosing the most suitable pipe size for each individual application.
- Page 25 The pipe work from the relief valve to the drain should be as short as possible and fall all the way from the water heater with no restrictions. It should have no more than three right angle bends in it. Use DN20 pipe.
