Premium Water Main MOT Survey
Specialist Incoming Water Supply Inspection
What Is The Premium Water Main MOT?
Most standard homebuyer surveys do not fully test the underground incoming water main, water pressure, flow rate, leak indicators, lead pipework, water hardness or suitability for modern plumbing systems.
Our Premium Water Main MOT Survey is a more detailed inspection designed for homebuyers, homeowners, landlords and renovation clients who want a clearer understanding of the condition, performance and compliance of the property's incoming water supply.
Using state-of-the-art digital diagnostic testing equipment, we assess:
- Static water pressure
- Dynamic water pressure
- Flow rate
- Pressure drop under demand
- Water hardness / TDS
- Active leak indicators
- Water meter presence
- External stop valve location
- Internal stopcock location
- Double check valve and drain off arrangement
- Incoming pipe material
- Lead pipe risk
- Shared supply risk
- Suitability for modern plumbing and heating systems
- General water regulations compliance observations
Following the inspection, you receive a professional written report with findings, photos, test readings, risk notes and recommendations.

These issues are often not discovered until after moving in or starting renovation works.

Water Regulations Compliance
As part of the inspection, we assess visible aspects of the incoming water supply arrangement for general compliance observations, including:
- Double check valve presence
- Drain off arrangement
- Accessibility of isolation valves
- General condition of incoming fittings
- Suitability of visible pipe materials
- Shared supply arrangements where identifiable
This can be particularly beneficial for older properties, renovation projects, boiler upgrades, unvented cylinder installations, heat pump installations, property purchases and plumbing system alterations.
