The check valve is a directional valve. Hot water needs to be piped from the top of the tank to the fixture, because that is where the hottest water in the tank is. If a return line is tied into the bottom of the tank, a directional valve (check valve) should be installed between the heater and the pump. That's what they taught me don't know if it really matter upstream or down stream. If you don't have a check valve the water could flow through the return line to the fixture instead of through the supply pipe and the water at the fixture might not be hot enough.

What is the purpose of a check valve on recirculating hot water system?
To prevent stratification of the hot water molecules into the cooler water as heat goes to cold
Can you provide a hot water recirculating pump installation diagram?
A hot water recirculating pump installation diagram typically includes a pump, check valve, bypass valve, and return line connected to the water heater and the furthest fixture. The pump circulates hot water to reduce wait times.
What does a check valve do?
A check valve restricts the flow of a liquid or gas in a piping system to one direction.
Can a check valve in a hot water system go bad?
Check valves can go bad, however I can't imagine where you'd have a check valve in a normal hot water system.
Your outboard leaks fuel out the air box?
The most likely culprit would be a flooding carburetor, which a good cleaning and possibly a gasket kit should cure. Other possibilities would include a blocked fuel recirculating check valve, or a broken reed valve.
Where is the check valve on a Ford Taurus fuel system 2000 24 valve v6?
check valve is location is on the brake boster vacuum hope this helps i just put one on the only check valve i know is for the emissions vapor purge system. check valve is on the top of the fuel tank.this will give you a check engine light with a evap failure code. or are you looking for the valve to check fuel pressure? that is on the fuel injector rail.more info will give more help
How to install a check valve properly?
To install a check valve properly, follow these steps: Determine the correct size and type of check valve for your system. Shut off the water supply and relieve any pressure in the system. Position the check valve in the correct orientation, ensuring the flow arrow points in the direction of flow. Use appropriate fittings and connectors to secure the check valve in place. Tighten all connections to prevent leaks. Turn on the water supply and check for proper functioning of the check valve. Remember to consult the manufacturer's instructions for specific installation guidelines.
What is the purpose of a check valve in a water heater system?
A check valve in a water heater system prevents water from flowing back into the system once it has been heated and circulated, helping to maintain consistent water pressure and prevent damage to the water heater.
Where is the check valve on a 1994 Jeep Grand Cherokee Limited 6-cylinder fuel system in pump in pump assembly or elsewhere?
The flow back check valve is in the pump.
Is the egr valve apart of the emission system?
Yes, the EGR (Exhaust Gas Recirculation) valve is a crucial component of the emissions control system in vehicles. It helps reduce nitrogen oxide (NOx) emissions by recirculating a portion of the exhaust gas back into the engine's intake, which lowers combustion temperatures. This process contributes to meeting environmental regulations and reducing harmful emissions from the vehicle.
What does an egr valve do on a 1999 Chrysler Town and Country?
It helps controll emissions by recirculating exhaust gasses back into the engine to lower combustion temperatures. When it goes bad the check engine light can come on, the idle can become unstable, and it may cause a misfire.
How do you pipe recirculating hot water?
Go from the top of your hot water tank and make your line go to every fixture and after last fixture go back to the tank and connect back into pump, make sure you install a check valve on line at pump
