Scope of Works

 

• inspect the cistern and flush mechanism to identify the fault

• adjust float and valve settings, reseal connections and replace washers or gaskets as required

• test multiple flush cycles and check for leaks at inlet, outlet and pan

• clean up, dispose of old parts and advise if a full cistern replacement is preferable

Time on Site

 

Most simple flush repairs take 30–90 minutes on site; replacing a concealed cistern, sourcing special parts or tracing hidden leaks can extend the visit to 2–4 hours

 

Questions to Ask Your Tradie

 

• can you diagnose and fix the cistern on the same visit, and will parts be charged extra?

• do you carry public liability insurance and provide a written estimate for the work?

• do you keep common replacement parts in the van (valves, seals, dual‑flush kits) or will you need to order them?

• how long is your workmanship guarantee and what does it cover?

• will you need to access a concealed cistern, loft or remove panelling, and are there extra charges for that?

• how do you handle contaminated water and what PPE do you use inside the property?

 

How to Avoid Surprises

 

• ensure clear access to the toilet, cistern lid and the stopcock

• remove floor mats, toiletries and items on the cistern lid before the visit

• check parking or permit requirements and tell the tradie when booking

• make the stopcock accessible and confirm whether water will need to be turned off

• advise the tradie of building or management rules (flats, communal access) before booking

• agree an authorisation limit for extra parts or labour so you know when they will call for approval
