Fresh water system help!!

[liltazboss]

Need help troubleshooting my fresh water system on 1985 Catalina C30

Water was running fine yesterday. Wanting to flush system so I drained all old water out by opening all faucets and draining out all water in tanks. Then filled water tanks and added system flush. When I turned on pump and opened faucets, no water flow. What am I missing? I can hear pump running but can't get water to flow at all.

Need advise to troubleshoot what is going on. Thanks!

You probably need to prime the pump. Look up the model online and read directions thereto.
