The check valve is inside the pump casing, so there is no separate one to buy or fit. Electrical and thermal protection is built in. A release screw frees the rotor if the pump has stood unused for months. The volute is epoxy coated for corrosion resistance.

For tank fed systems. It boosts what the tank gives it, so it will not help if the problem is on the mains side.
