The SharkBite Check Valve is a general purpose, spring loaded check valve that can be installed in seconds on copper, CTS, CPVC, and PEX. The SharkBite check valve can be installed horizontally or vertically and prevents the reverse flow of water through the water supply line.
- 1/2" X 1/2"
- 3/4" X 3/4"
- 1" X 1"
How much flow will be restricted by the 3/4 inch version. I have 15 GPM at 42psi. What would be the flow rate after inserting the back flow preventer?
The check valve requires 2 PSI to open it. You shouldn't see a dramatic flow rate drop. Maybe a few PSI and fraction of GPM loss.

Does sharkbite make an expandable fitting for a pipe connection where there is no way to pull or move the pipe to connect together
No. All our fittings are push to connect. We do offer slip couplings but these are designed to repair a gap (up to 2 inches) in a pipe and not to extend the length of the pipe.

Can I put one of these on a plastic hose from a fountain pump?
Our SharkBite fittings only work on Copper, PEX, CPVC or PE-RT pipe. If your hose is not one of these, we do not recommend using our fittings.

Can this valve be used to drain a water line for the winter. For example when I shut the water off to my cabin and the pressure drops it will drain the water in the line and when I turn the main water on the pressure will close the valve
This product is designed to prevent back flow. This would not be something that will "auto drain" your line. You would want to use a ball valve to prevent water from the main line going into your house.

Can I use this check valve to replace a Taco 218 flo-check valve on my hot water heating system? The Taco valve prevent the flow of hot water until the calculator pump is activated
Our check valves are designed for a one direction flowing system. If your project requires the water flow in the opposite direction in particular cases, our fitting will not work with your system.
