Hot/Cold Heat Trapper Nipple Set for Water Heaters
Designed for water heaters, these trapper nipples save you money by lowering energy costs related to your water heater. The Heat trapper includes two dielectric waterway fittings, a cold water inlet (blue) with a thermoplastic ball that floats and a hot water outlet (red) with a fluoroplastic ball that sinks. When water flow stops, both balls move to their seats. Each seat is equipped with a safety relief port. When water is not flowing, heat is effectively trapped in the water heater. It cannot escape into the piping system thereby reducing standby heat loss. Because the water heater does not cycle as often, less energy is required and utility bills are reduced.
3/4" MPT Heat Trapper Nipple Set (Hot & Cold) = $10.24

Frequently Asked Questions
Q. "Why is there a hole near the top of your dip tubes?"
A. The reason for the hole is to break siphonage effect when the water is shut off and there is a drain down situation (caused by such things as a valve or a leak that is below the waterheater). A common example would be in a mobile home water heater, where the water supply is nearly almost always under the floor. If the water gets shutoff (for whatever reason), without that hole, the diptube could possibly backsiphon (empty most of the water and drain it to the level of the inlet on the cold water diptube), burning up the elements or possibly allowing the gas burners to damage the near empty water heater. Bottom line, it's for safety.
Q. "I have a rattling sound coming from my water heater when the hot water is running?"
A. Check to see if you have check valve type nipples installed on the top of your water heater. They generally look like ordinary galvanized nipples and so sometimes it is hard to tell if they are installed. Some water heaters come with them. They are a great idea because they can save some energy, but they also can be very annoying.
Q. "You show a CSA Rating for the temperature and pressure relief valves. What does the CSA rating refer to?"
A. The CSA rating refers to the temperature steam rating of the temperature and pressure relief valves to confirm they are in compliance with ANSI standard Z21.22. They are tested by a nationally recognized testing laboratory that periodically inspects products to make sure they are in compliance. This rating is used to size temperature and pressure relief valves to ensure they will discharge adequate water as needed when the temperature exceeds the BTU input rating of the tank for which they will be used. The temperature and pressure relief valve must be able to discharge more BTU's than the heater is capable of putting into the water.
