ABSTRACT OF THE DISCLOSURE A faucet spring utilized to urge the faucet seal member into sealing contact with the rotatable valving member and prevent large debris, such as valve washer screws from previous faucet assemblies, from contacting the valving member under the fluid pressure. The coil spring has a substantially frusto-conical configuration with a smaller diameter upper end which engages the seal and urges it against the valving member. The larger diameter lower end of the spring engages an annular shoulder of the counterbored inlet passage of the valve assembly. The lower end of the spring also includes an obstruction member formed as an extension of the coil spring which extends into the opening of the spring's lower end to prevent large debris from traveling through the spring and seal. As a result, the faucet spring provides the added function of preventing potentially damaging debris from contacting the valving member.
