What is the bypass on pool pump used for?
The recirculate setting on a swimming pool filter is actually used to bypass the filter mechanism. 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.
What is bypass valve?
Bypass valves are designed to divert steam from one part of the system (such as power generation or process steam such as paper and pulp production) to a reheat or exhaust piping to safeguard equipment from over-pressure. Designed to cope with pressure and temperature differentials, they are used in many applications.
Is bypass the same as circulate?
CPB mechanically circulates and oxygenates blood for the body while bypassing the heart and lungs.
What does bypass waste mean?
Bypass your filter so algae doesn’t flow back into your pool with vacuum to waste. If you vacuum to waste, you are bypassing the filter all together and you don’t run the risk of the algae bypassing your filtration and/or sanitation system and kicking back out into your pool.
Which valve is main drain in pool?
On the bottom of the float valve there is a small teardrop-shaped flap attached to the valve with a single screw. This flap is responsible for the regulation of flow between the skimmer and the main drain. If the flap is closed, the main drain is the sale port through which the water flows out of the pool.
Should a pool heater be bypassed when not in use?
Not Using the Heater: If the heater gets very little or no use, then it should be bypassed. A broken or non-operational heater should NEVER have any water flowing through it. No need to bypass the heater when adding a small amount of chemicals for regular or weekly water maintenance.
How does a heater bypass valve work?
The heater control valve is a cooling and hvac system component that is commonly found on many road going cars and trucks. When the valve is opened, warm engine coolant passes through the valve and into the heater core, so that hot air can be produced from the vehicle’s vents.
How does a bypass valve work?
Pressure bypass valves serve to control pressure in a system by diverting a portion of the flow. Typically they bypass fluid from the outlet of a pump back to the reservoir. The schematic at right shows a Pressure Bypass Regulator being used to control the pressure at the exit of a pump.
Why is a bypass check valve used?
When you blow out, it closes the valve and allows the air to flow out into the water.” Bypass valves are important in any system through which water or oil is pumped to maintain an even pressure and keep the system operating. Construction equipment in particular relies on bypass valves to relieve pressure build-up.
What kind of diverter valve do I need for above ground pool?
Diverter valves can be used on PVC plumbing for in-ground or above ground pools. They can be fitted vertically or horizontally. There are two types of diverter valves – the positive seal, and non-positive seal. Positive seal – Completely seals the valve opening preventing any seepage.
What are the different types of pool valves?
The ball valve uses a metal (usually copper) sphere with a cored center to allow water through. Butterfly valves use a spinning paddle plate to adjust water flow. A quarter turn of the handle spins the paddle sideways releasing the flow. Butterfly valves are unique in the sense that their element remains in the direct path of flow at all time.
How does a spring check valve work in a pool?
The valve is plumbed with the plunger facing the flow of water. As your pump builds pressure, the plunger will open allowing water to pass. The spring check valve is available in various spring tensions so a user can adjust the flow needed to open the valve.
Why do you need gate valve for above ground pool?
Gate valves are installed on above ground pools for their ability to shut off hose or PVC piping while filtering equipment is serviced.
