Hello
Looking at other houses in my area, it seems that there should be a hopper below my bath, sink and shower waste pipe, where it exits the outside wall. The previous owner had instead connected this 40mm pipe to a standard down pipe, using silicon seal to fill the mismatch in pipe size. The down pipe goes straight to a gully. The plugholes always smell of drains in the bathroom.
So last week I bought a hopper and installed it below the waste pipe, on the top of the down pipe. The drains smell has now gone away. However, when I empty the bath, the hopper overflows badly. I've checked and it's not blocked.
Is the position where the waste pipe enters into the hopper critical? I could adjust that so it is exactly above the down pipe opening. Or is there anything else I can do?
I got the hopper from Wickes and it is approx 25cm by 8cm. I've seen ones the same size fitted on other houses in the area.
Ta for any advice
