After many attempts to resolve a sliding seat including 3 replacements i am still having to repeatedly re-attach the seat to a fixed position. I have tried an extra washer at 1 side to no avail. The current seat is a Â£40 best quality i could find and it is also moving now after a reasonable run of about 4 months in place. Could it be the design of the WC? I have had the same WC for 6 years & always had a seat that inevitably ends up slipping about.
any help in this matter?
