The toilet flush stopped working properly, then within the week (good timing) the inlet valve on the ball cock arm started to fail. Plumber said this was a £150 job. I bought the inlet valve arm for £8 and thought I would see how tricky it would be to rummage around myself before looking at buying a new syphon flush unit or calling a plumber.
This 'simple' replacement ended up being the hardest bit because the connection to the old pipe was different and I had to replace the lot, then the joining copper pipe started leaking.
While I was down there I thought I would look at the broken syphon filter. Amazing news. The one fitted comes apart so I didn't need to take the whole ceramic cistern off too look at the broken bit.
Even better, it was just this filter thing that was all ripped up. If I could change that I wouldn't need a new syphon and I wouldn't need to remove the cistern top.
However all the on line vids with this rip just told you to replace the unit. I didn't understand why. I looked up the material and it appeared to be nothing more than floppy plastic held on with a washer. So I just cut my own out of a plastic folder.
I realise none of this is amazing, but considering how utterly lost I was when I couldn't even unscrew the copper inlet pipes and how ridiculously easy it looks now I know what's involved. . .I think it is mildly amazing.
We should all learn this shit at school really. Joining and sealing pipes, olives, syphon, filters, valves. . . Its not that hard, it's just the 'not knowing'.
I've saved myself about £150.
