Plumbing Pump and Engine Servicing Guide

Scope of Works

• Isolate power and water, drain the system and protect the work area.

• Strip and inspect pump/macerator casing, impeller, non‑return valves and electrical “engine” (motor, capacitor).

• Clean & descale housing and pipework; flush debris from pressure vessel or macerator chamber.

• Replace wear parts – seals, diaphragms, capacitors, microswitches and O‑rings as needed.

• Lubricate, re‑assemble & rewire to manufacturer torque settings; fit new gaskets.

• Pressure/flow test under load, adjust pressure switch or flow sensor, check for leaks and vibration.

• Issue service report with test readings and recommended maintenance intervals.
  

Typical Cost (inc. VAT)

Time on Site

1 – 3 hours for straightforward service.Longer if: unit is hidden behind boxed‑in pipework, severe limescale requires repeated chemical soaks, or pressure vessels need draining/refilling.

Questions to Ask Your Trade

1. Are you manufacturer‑approved for my pump brand (Saniflo, Stuart Turner, Grundfos, etc.)?

2. Does the quoted price include all parts and descaler, or will those be billed separately?

3. Will you bench‑test the motor and capacitor or just clean the wet end?

4. How long is your workmanship warranty on repairs and replaced components?

5. Can you provide a flow‑rate/pressure report after servicing for my records?

6. What preventive maintenance schedule do you recommend between services?

7. Do you carry spare pumps in case mine is beyond economic repair?
   

How to Avoid Surprises

• Give clear access to the pump cupboard and any isolation valves.

• Reserve nearby parking for a van carrying heavy pump spares.

• Tell the engineer if caustic drain cleaners or bleach have been used recently in a macerator.

• Confirm in advance whether out‑of‑hours rates apply if testing runs past 6 pm.

• Ensure safe electrical isolation (fused spur or breaker) is available for motor work.
