Here's a great firm to use for things like this in the future, I've tried one or two of the touch-up kits in the past and for me, they were a bit of a failure
Hi everyone. Just had the same problem with the flush - it suddenly lost pressure, so although it would pump into the bowl, it wasn't a good flow. After reading the various messages, I stripped out the pump (the sealant was hard to unstick!) and found that the clip on tbe base was OK, but it was the bottom of the pump body which had broken. New pump on order from Leisureshopdirect.
Also I guess it has been repaired before, because after undoing the two screws below the handle, I found that the main bezel was held by 1 countersunk screw, one round-head screw, and two invisible screws!! So, now need some additional screws to hold it all together properly!
Good to be able to benefit from the advice of others on the forum (even if it is several years after the previous post LOL)
