My shop has a very old high-level cistern, made of rubber I think. The supply and flush pipes are lead.
The diaphragm is split, as the chain takes a lot of pulling to flush. Most siphons need to be completely removed to replace the diphragm, but I don't really want to disturb the lead flush pipe, as it has many layers of paint, and hasn't been disturbed for decades. I forsee many more problems.
I notice that the plastic (i think) siphon fitted has 3 screws near the base inside the cistern. If I remove these screws, can I split the siphon and not need to disturb the joint under the cistern?
