I have had to remove a broken 12 inch x 12 inch, salt glaze, drain hopper from the base of a down flow pipe.
The inside diameter of the pipe in the ground is 6 inch (150mm) while the external dia. is 9 and a half inches. (240mm)
The only drain hoppers I can find have an outlet pipe of 100mm. (4 inch)
I have not got the room to add a load of reducers as it would raise the new hopper to a ridiculous height.
This problem must have happened to others.
Any place still stocks sells hoppers to fit 6 inch pipes?
Any suggestions, please?
