In all the couplings on the generator and acid-chamber a lead washer, in the couplings of purifiers and fountains leather washers, must be placed to keep all joints tight and prevent loss of gas, or access of air. Occasionally disconnect and examine the pipes of apparatus. If obstructed, they should be cleaned out.

Discharge from time to time some water under pressure of gas through all the valves and connecting pipes for rinsing, thus avoiding all danger of collapsing the fountain linings.

The flanges and stuffing boxes of the agitators in generator and fountains repack frequently with cotton wick or hemp well soaked in tallow, or, what is still better, paraffine, which resists the action of acid. Screw tight with the cap again. Also repack all the valves. All the movable parts should be kept well lubricated, care being taken not to allow the oil to become gummed. Lubricating oil (Vulcan oil) serves the purpose.

Examine the safety valve occasionally to see that it is in working order.


To find out leakages charge up the apparatus, close all valves and caps tightly and watch the pressure gauge. If the latter shows a gradual decrease, the caps and couplings need repacking or new washers.

Storage Of Apparatus

At the close of the season, or whenever the generator and fountains or parts of them are no more used, fill them full with pure water. After standing a few days to absorb the gas, empty and put away in a dry place.

Re-Lining Of Fountains

A fountain ought to be opened and re-lined at least once in three years if it is sheet lined. Even if block-tin lined, it ought to be looked after frequently. If the lining of the fountains is leaking, the carbonated water will absorb iron (in an iron fountain) and copper (in a copper fountain). While the first is not unwholesome the second is decidedly so. Send your fountains to the manufacturer of the apparatus, for re-lining, to insure a good job. Never put this work in the hands of an inexperienced man, as the re-lining has to be seamless and of pure tin to prevent contamination of the beverage.
