As such, a common location for a check valve is on the incoming suction pipe, in front of the filter pump. For best results with pump priming, especially for pumps lifting more than 24” from the water surface, the check valve should not be installed directly against the pump intake, but 12”-18” in front of the pump.
Without one the heater can be exposed to concentrated chlorine that siphons backwards through the plumbing system. … Chlorine does damage heaters in high doses, and chlorine feeders do need to be protected with check valves to stop the chlorine from them from moving backwards into the heater.
Thereof, Do I need a bypass for my pool heater?
If your system will move more water than the maximum that your heater can safely handle then you will require an external bypass to be installed. Most new heaters have internal bypass systems installed to prevent from sending too much flow through the heat exchanger but an external bypass may be preferable.
Also to know is, What is the point of a check valve? Check valves are generally installed in pipelines to prevent backflow. A check valve is basically a one-way valve, in which the flow can run freely one way, but if the flow turns the valve will close to protect the piping, other valves, pumps etc.
Subsequently, question is, How do you fix a stuck check valve?
Also, What is the bypass on pool pump used for?

How do you install a pool heater bypass valve?
What does a pool check valve do?
A check valve is a one-way flow valve, with a purpose to keep water from flowing backwards or to prevent cycling of water in solar systems or bypass loops. Check valves are used in pool, spa and fountain plumbing to keep water flowing in only one direction.
Does a pool heater use a lot of electricity?
Heat pumps will use around 5,000 watts or 5 kilowatts per hour per 100,000 BTU’s. For a typical size 100,000 BTU heat pump, that’s 5 kilowatts per hour. The average for electricity in our area runs $. 16 cents per kilowatt hour.
How can I heat my above ground pool cheap?
How long does a pool stay heated?
Overall, a heat pump usually requires between 24 and 72 hours to heat a swimming pool by 20°F (11°C) and between 45 and 60 minutes to heat a spa by 20°F (11°C). So now you know some factors that affect your swimming pool’s or spa’s required heating time.
Should I run my pool pump on filter or recirculate?
Recirculate allows the water to flow out of the pool and back into it again without running through the sand or diatomaceous earth in the filtration system. … It’s best to run the pool filter for 6-8 hour before shock treatment, and to schedule the shock when the sun has set.
How much does it cost to heat an above ground pool?
Type of Heater Cost per Year Cost Per Month
——————- ————– ————–
Propane $2,500-$10,200 $200-$850
Electric Resistance $2,100-$7,200 $175-$600
