What to do when your water heater drain plug comes out?
Assemble the three tools and use those to easily remove a water heater drain plug in seconds. (Remember, righty-tighty, lefty-loosey.) Be ready for a gush of water as the plug comes out. A bucket on the ground below the water heater is helpful. Throw away the old plug so you’re not tempted to reuse it someday.
What to do if your pool heater manifold is cracked?
Assist the draining by blowing out the heat exchanger through the pressure switch fitting with low pressure compressed air (less than 5 PSI or 35 kPa). Remove the Water Pressure Switch. Plug the port in the manifold to prevent bugs and dirt from getting into the manifold. Drain the plastic inlet/outlet manifold through the outlet pipe.
Where does the water go when the pool heater is off?
The heater uses a thermal regulator, which prevents water from going through the heat exchanger until the water heats up when the heater turns on. When the heater is off, all of the water goes through the internal bypass. There are two drain plugs on the MasterTemp.
What kind of plug is on back of pool manifold?
You have to remove the front panel to get at the second plug which will let you drain the back of the manifold and heat exchanger. The rear plug is made of zinc typically.

How does a bypass valve work on a pool heater?
A bypass valve is put in place near the intake to stop water from flowing through the heater when it’s not in use. When in bypass, the heater’s water flow switch (i.e., the pressure switch) should open, and the heater will not run. The bypass valve is shown as closed in the picture below.
