Soft water cisterns must be ventilated to prevent stagnation.
Storage tanks should have an extra large sediment draw off cock to be used solely for cleaning tank. It is a regrettable fact that the majority of storage tanks are seldom cleaned.
Hammering, rumbling or snapping in the range boiler or hot water pipes is caused from sagging of the pipes, causing traps or dips or from stoppage in the water front.
Water fronts should never be connected directly to the city pressure. The cold water supply to the water front should be taken from the bottom of the range boiler.
Use a small offset between sink and sink trap as shown in Fig. 43, page 96. This will prevent the annoying constant dripping noise in the sink.
Very often it will be found economical to waste all the fixtures but the closet, into the 2" sink stack. In cases of this kind the closet need not be revented as it is the only fixture wasting into the 4" stack.
House sewers should have a pitch of 1/4 to the foot.
Automatic closets and urinals should always be used in schools and factories.
In cities where the water pressure is increased in case of fire, a pressure regulator should be used, or the house should be supplied from a tank in the attic. If the tank system is used, the extra fire pressure does not affect the fixtures or piping.
It is poor practice to connect sediment pipe from range boiler to the sink trap. It is far better to use a compression bibb, as this precludes the possibility of waste, and the plumber knows for certainty that the system is drained.
File or drill a small hole in boiler tube about 6" from the top to prevent syphonage of boiler.
The circulating pipe should be of the same size as the flow pipe, and to insure best results, take supply to fixtures from return or circulating pipe.
Hot water faucets should be at the left hand when facing the fixture.
Stops should never be used on range boiler supply. Always use stop with waste to give vent to boiler when water is shut off.
Coils in furnaces should be placed above the bed of fire, not in it.
Check Valves Should Never be Used on Circulation.
While this is true as a general proposition, there are some cases where a check valve is necessary, to prevent the water from reversing in the circulating pipe. In cases of this kind use a horizontal check valve and place it as near the boiler as possible. The check valve should be installed so that the water cannot flow through check valve from boiler.
