For example, your bushing could have a 3/8 male thread on one side and 1/4 female threads on the other.
The cold water gate valve must be left open while a water heater is in use. Check the relief valve periodically to make sure it opens and then closes again. Remember that water coming from the relief pipe may be very hot. The relief line shown in Fig. 1 is a safety feature. It directs any hot water the relief valve releases toward the floor.

Compact plumbing design is the best way: fixtures that use hot water are grouped close to the water heater so that the pipes are short and no one has to wait too long for hot water.

Many water heaters develop leaks at the pipe connections on top. Manufacturers usually provide two special steel pipe fittings that are threaded into the top of the steel tank. It's typical for steel water heater tanks to have the cold water inlet pipe and the hot water outlet pipe connected to these fittings using copper fittings and pipes.
The release valve at the top of the hot water heater has developed a leak or is starting to fail. That valve exists to release water because temperature and pressure are related linearly. When temperature goes up, pressure goes up. The release val
Residential hot water lines are often kept small to minimize heat losses. In larger pipe you have to drain a lot more water before it gets hot at the tap and all the residual hot water will loose its heat before the next use. The water heater tank has almost no damping effect on downstream piping.
