Rodent advice
Rats can enter a property through faults in its drainage system. A drain survey helps us understand the route before deciding whether a rat valve is suitable.
Why we check the drains
During the rodent clearance described in this original case, we fitted a one-way rat drain blocker as part of the work. This type of device allows waste to pass through while restricting rats travelling back towards the property.
A valve is one part of a plan. Repeated rat activity can also be linked to damaged pipes, redundant connections or other openings, so the first step is to investigate rather than assume a valve will solve every problem.
A survey before installation
We assess the drainage layout and access, and may recommend a camera survey to look for possible entry routes. The location and suitability of any valve depend on what the survey finds.
Repairs and regular checks matter
If a drain fault is found, we strongly advise having it repaired by a drainage specialist. A rat valve is a moving component in a drain and is not necessarily a permanent resolution. It should be checked at least annually; twice a year is preferable.
Looking at the whole property
Drain checks sit alongside an inspection for other entry points, food sources and signs of activity. We explain the findings and recommend treatment, proofing or specialist repairs appropriate to your property.
