I'm hoping for some help here. My admiral took a shower on the new to us 1996 Catalina 380 Saturday and the shower sump pump besides being way noisy, also seemed to work really slow. Any chance there is a filter somewhere that protects the pump I couldn't find? I didn't look too hard as I was already busy putting a new faucet in the fwd vanity sink but I'd really appreciate any help with this.
