How to raise a 300mm Everhard stormwater pit by about 50mm?

Hi

Any suggestions on how to raise a 300 mm everhard storm water pit by about 50mm ?  Are there any storm water pit risers that would be suitable or could be cut down to make them suitable ?

thanks in advance

Hi @rob-4x4,

Our Special Orders team at your closest store can order a 300 mm Everhard pit riser, but note that it increases the height of the pit by 150 mm. It is possible to cut it down to achieve the 50 mm increase, but keep in mind that the riser has fins on the side that would also need to be trimmed. With some careful modification, the standard 300 mm pit riser can be made suitable for your needs. However, it would be best to speak with a licensed drainage specialist as to whether your modification meets standards. They might also need to modify the pit for you to comply with regulations.

Please let me know if you have any questions.
