1 Claim.
This invention appertains to new and useful improvements in plumbing systems and more particularly to improvements in hot water lines to faucets, the principal object of the invention being to provide a plumbing system which will alford hot water at the faucets at all times.
Another important object of the invention is to provide a plumbing system in which hot water circulates continuously for the purpose of affording hot Water at all times at the faucets in the system.
Other objects and advantages of the invention Will become apparent to the reader of the following specification.
In the drawing:
The single View represents a fragmentary elevational view of the pipes of the system.
Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 denotes a hot water heater for the hot water tank 6. This tank is usually located in the basement below the iirst floor 1. The system may extend up one or more floors 8.
Numeral 9 denotes a cold water supply pipe to the T-tting Il) above the tank 6, downwardly from which extends a pipe Il which terminates in the tank adjacent the bottom thereof. A cutoif valve I2 is provided in the pipe 9. At one side of the fitting I is a T-tting I3 from which the pipe I 4 extends, and from this pipe I4 the cold water supply branch I5 extends to, for instance, the kitchen sink (not shown). Other branches I6, I1 and I3, of course, extend to a bathroom wash bowl, tub and commode, respectively, (not shown).
At the other side of the T IB is an elbow I9 to which attaches the hot water return pipe 20. At one side of the T-itting I0 is a check valve 2| to prevent the cold Water from the pipe 9 getting into the pipe 20, while numeral 22 represents a check valve preventing loss of hot water from the pipe into the cold water pipe 9.
Numeral 23 denotes a pipe from the upper portion of the tank 6 for supplying hot water by branch lines 24, 25, 25, for instance to a kitchen sink, a Wash bowl, a bath tub, respectively.
At the end of this pipe 23 a joint such as a pair of elbows connected together to provide a degree return joint, connects the pipe 23 with the return pipe 20.
It can now be seen that hot Water passes from the tank 6 along the pipe 23 to the various hot water faucets (not shown) and returns by way of the pipe 20 to the fitting I0 and the lower portion of the tank 6. Thus it can be seen, that there is a continuous circulation of the hot water which will afford hot water instantly at Whichever faucet is opened.
While the foregoing specification sets forth the invention in specic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.
Having described the invention, what is claimed as new is:
A plumbing system comprising a hot water tank, a T-tting at the top of the tank having a pipe extending downwardly into the tank to terminate adjacent the bottom thereof, a cold water supply pipe to one side of the T-tting, a hot water supply pipe extending from the top of the tank, and a return pipe from the hot water supply pipe connected to the other side of the T- tting, a cold water service riser extending from the cold water supply pipe, a check Valve in the latter pipe between the riser and the T-fitting to prevent hot water from reaching the riser, and.
a check Valve in the return pipe adjacent the T-fitting to prevent entrance of cold water from the cold water supply pipe into the return pipe.
