What Size Copper Pipe For Water Heater

Pipe Size Based On Fixture Units

We don't know of any specific minimum in the International Building Code (IRC) or Florida Building Code (FBC), simply the sizing of h2o distribution pipes is based on a combination of "fixture units," which is a number assigned to different types of plumbing fixtures co-ordinate to their probable water usage, and the length of piping in the arrangement. To complicate things further, the calculation also requires an allowance for the friction in the pipes based on type of pipe and number of elbows.

But, on average, a 1/two" distribution piping is only good for about three fixture units, while a three/4" pipe is rated at approximately x fixture units. The hot water fixture rating of a bath is i.5 fixture units, and a kitchen with sink and dishwasher adds 1.ix fixture units That'due south 3.4 already, and we oasis't even added a laundry at 1.8 fixture units. And so a 3/four" inlet pipe would be the minimum for nearly homes.

Just to be sure, nosotros checked with our plumber, James Freeman, of J.Westward. Freeman Plumbing in Gainesville. "You need to know how many fixtures are existence fed by the water heater, and so utilize the tables in Appendix E of the Florida Plumbing Code," according to James. "About homes will need three/iv". Some of the older houses in boondocks, though, piped the entire hot water organization in 1/ii", to get the hot water faster and cut down on waste."
