Regular inspection and maintenance of drains is highly recommended, in order to detect any issues such as cracks, blockages, or tree root ingressions. Drain issues, when left, can lead to extensive damage.
You are usually responsible for the drains within your property boundary.
Usually, drain surveys are carried out by accessing a manhole. This is an entry point to the drainage system, which is usually covered by a thick metal lid.
Drain Surveys
Whilst it is possible to carry out a drain survey without a manhole, this is a professional job and requires skilled tradespeople to carry it out properly.
Sometimes manholes are hidden. A drain expert will be able to use specialist equipment to find its location, in the event that it cannot be found by the property owner.
A drain specialist is equipped for every eventuality – Whether that be an accessible manhole, a hidden manhole, or no manhole at all.
Sometimes this will involve conducting the survey via access to an external stack, or by using professional tools that allow access into an existing pipe. .

Choosing the right size of manhole cover
A manhole cover is a removable plate that sits over an opening into the drainage system. It stops people falling in and keeps unauthorised people out of pipes and drains, while still letting engineers in when access is needed for inspection or a survey.
Sizing can be confusing. Covers are made and listed by their clear opening, which is the size of the hole they fit, not their overall dimensions. A cover described as 600 by 450mm, for example, may measure nearer 650 by 550mm overall but is designed for an opening of 600 by 450mm.
Getting the size right matters. A cover that is too small for the opening is likely to fail. One that is too large can sometimes work, but only if it has no reinforcement on the underside that would stop it sitting properly. The safest approach is always to source a cover made for the exact size of the opening.
