Rated 5 out of 5 by from Toilet Syphon Toilet Syphon 8 inch. Fitted into my 25 year old toilet sistern tank which contained a filler valve unit ,and a flush handle on the RHS. There LHS on the tank contained the overflow pipe causing the syphon unit to jam against the filler valve. The overflow pipe was removed, and the filler valve moved over to the LHS together with the inlet water pipe. The hole was plugged with a new plastic plug.This gave the Syphon unit much more space, and after reconnecting the flush handle with a slightly longer linkage, everything now works very well with first time flushing every time.

Rated 5 out of 5 by from Worth the money Bought this one as I had to change the diophram on my old syphon, well worth the extra money to avoid having to take the whole thing apart again. It has it's own overflow as well which avoids having to have a seperate one which I did. Closed up the hole and much neater.

Rated 5 out of 5 by from Useful replacement I am pleased with the product and the delivery. Unfortunately it doesn't alway flush on the first try. I am uncertain as to whether I should have removed one of the white plastic grommets. The instructions were rather confusing on this point.
