Under Chassis Wash Benefits
- Efficient undercarriage cleaning
- Built for outdoor use
- UKCA and CE‑certified, strong and reliable
Option 1 - Wash Down Pit
The Project
Cleaning of vehicles using a Wash Down Pit solution.
The Problem
In limited spaces, numerous vehicles require a wash-down from the top to the undercarriage of the chassis in preparation for an MOT.
Solution
The features of a wash-down pit include a large built in settlement tank with a weir, a flow forge floor and hose connections. This style pit allows a vehicle to be washed above and below at the same time, saving on time and space in the workshop and only requires 10m of yard space.
Outcome
It allows the customer to prepare all vehicles for MOT ‘s as well as routine cleaning efficiently.

Option 2 - Half Pit/Half Ramp
The Project
Cleaning of vehicles using a combination of wash down pit and a ramp solution.
The Problem
In limited spaces, numerous vehicles require a wash-down from the top to the undercarriage of the chassis in preparation for an MOT.
Due to many garages having logistical constraints in their premises such as width and height as well as challenging ground conditions. Premier Pits designed this bespoke design.
Solution
The features of a wash-down pit including ramps either side of it, allows the end user to get a facility which accommodates the water to be collected into the built in settlement tank located in the pit and the ability to wash the parts of the vehicle from the slab. The yard space required for this is 19.5m yard.
This pit has tanks with a weir (the same as a wash down pit), with the floor being constructed of flow forge floor (so water drains through it) and hose connection to facilitate washing tools. As the client’s business was located on gravel/sand ground conditions we wanted to reduce the risk of a wash down pit installations having problems with ground conditions and temporary works costs. Therefore, we designed a half pit/half ramp solution, to mitigate costs with additional ground works, but allowing operatives to enter a shallower pit once the vehicle was driven onto the ramp.
Outcome
It allows the customer to prepare all vehicles for MOT ‘s as well as routine cleaning efficiently. This solution works commercially to clients who have logistical restrictions as well as difficult ground conditions.
