Why Is My SEAFLO SFDP1-030-045-33 Leaking at the Pump Head?

Exact model: SEAFLO SFDP1-030-045-33

Safety: Disconnect the relevant power source and isolate moving, hot or pressurized components before service.

A.

Start with the accessible checks

What this suggests: A leaking SEAFLO 33-series head may be an incorrectly seated cone-seal fitting, a damaged diaphragm/pressure-switch membrane, a cracked housing or a loose head assembly.

What to do

  1. Isolate power, close water and relieve pressure.
  2. Dry the complete head and locate the FIRST wet spot.
  3. Detach and inspect the SEAFLO-specific tapered fittings and matching O-rings; clean the mating seats and replace cut seals rather than applying random PTFE tape to the manufacturer's cone seal, whose fragments may contaminate pump valves.

Still not fixed? Continue to the next check.

B.

If the problem remains after the first checks

What to do

  1. If leakage is from the head joint or switch region, use the correct model and production-date service kit for diaphragm or switch membrane and restore the manufacturer's fastening pattern. Replace a cracked plastic head, not glue it.

Confirm the repair

The head, connectors and switch stay dry over several pump starts and closed-tap pressure holds.
