The Annual Plumbing Checklist Every Landlord Should Complete Before a New Tenant Moves In

Preparing a property for new tenants involves more than a quick clean and fresh coat of paint. Taking the time to carry out a basic plumbing inspection can help prevent emergency callouts, costly repairs, and tenant complaints later on.

Whether you own a single rental property or manage a portfolio, this annual plumbing checklist can help ensure everything is in good working order before a new tenancy begins.

1. Check for Visible Leaks

Start by inspecting all visible pipework throughout the property.

Look under:

• Kitchen sinks

• Bathroom sinks

• Toilets

• Utility rooms

• Boilers

  
  

Even a small drip can cause damage over time, leading to damp cupboards, damaged flooring, and increased water bills.

Signs to watch for include:

• Water stains

• Damp patches

• Mould growth

• Swollen woodwork

2. Inspect Bathroom Silicone Seals

One of the most overlooked causes of water damage is failed silicone around baths, shower trays, and sinks.

Over time, silicone can crack, shrink, or separate from surfaces, allowing water to seep behind tiles and into walls or floors.

Check for:

• Gaps in the sealant

• Cracking or peeling silicone

• Black mould that won’t clean away

• Signs of water damage around baths and showers

  
  

A simple reseal can often prevent much larger repair bills in the future.

3. Test All Taps and Toilets

Turn on every tap in the property and check for:

• Dripping taps

• Poor water pressure

• Slow drainage

• Leaks around connections

  
  

Flush each toilet several times to ensure:

• The cistern fills correctly

• The flush operates properly

• There are no leaks around the base of the toilet

  
  

4. Check the Boiler and Heating System

A reliable heating system is essential for tenant comfort.

Landlords should ensure:

• The boiler is operating correctly

• Radiators heat evenly

• Boiler pressure is within the recommended range

• Any faults are investigated before tenants move in

Annual boiler servicing is not only good practice but can help identify issues before they develop into expensive breakdowns.

5. Bleed Radiators if Necessary

Cold spots on radiators can indicate trapped air within the heating system. Bleeding radiators can improve efficiency and help ensure tenants receive consistent heating throughout the property. After bleeding radiators, remember to check the boiler pressure and top up if required.

6. Locate and Test the Stopcock

Many tenants have no idea where the main water shut-off valve is located.

Before a tenancy begins:

• Confirm the stopcock is accessible

• Ensure it turns freely

• Inform tenants of its location

  
  

In the event of a leak, quick access to the stopcock can significantly reduce damage.

7. Check for Signs of Hidden Water Damage

Look for:

• Stained ceilings

• Peeling paint

• Musty smells

• Damp patches on walls

• Loose or warped flooring

  
  

These can all indicate plumbing issues that should be investigated before tenants move in.

8. Ensure Drains Are Flowing Freely

Slow-draining sinks, baths, or showers can quickly become a tenant complaint.

Check:

• Kitchen sinks

• Bathroom basins

• Baths

• Shower trays

Addressing minor blockages early can prevent larger drainage problems later.

Why Preventative Maintenance Matters

Many plumbing emergencies start as small issues that go unnoticed. Taking a proactive approach before a new tenancy begins can help reduce maintenance costs, avoid tenant disruption, and protect your property from unnecessary damage.

A thorough plumbing inspection can provide peace of mind and help ensure your rental property is ready for its next occupants.
