I recently replaced the fill valve on our toilet.
Of course it went disastrously wrong.
The cistern is filling at a glacial pace, after 30 minutes I gave it up as a bad job.
Looking around online, I think it's because of a flow restricter. There was a plastic blue one in the packaging, looking in the pipe, there's another one which I pulled out.
They look so different though that I'm scared the white one is actually something else essential to the entire valve.
The instructions don't even mention flow restricters and I can't find anything online that looks anything like that white thing.
Does anybody know if I'm safe to put the blue one in, or just do without either?
