The use of a check valve will slightly reduce the amount of air delivered because of resistance.</div><div>2. If you receive the check valve and find that it does not vent after the connection, please check if the installation sequence is correct. If it is correct, please disassemble the stop valve, and gently squeeze the vent by hand. Sometimes it is because that the rubber is slightly stuck due to high temperature.</div></div></div>
