It should not be necessary to stock a large number of spare parts. Past plumbing troubles may give some indication as to the kind of parts most likely to be needed. Spare parts should include:
Faucet washers and packing.
One or two lengths of the most common type and size of piping in the plumbing system.
Several unions and gaskets or unions with ground surfaces.
Several couplings and elbows.
A few feet of pipe strap.
An extra hose connection.
Grouped below are emergencies that may occur and the action to take. The name, address, and phone number of a plumber who offers 24-hour service should be posted in a conspicuous place.
