I noticed a small leak on the pin that activates the micro switch on the diaphragm assembly. That is easy to fix by replacing the diaphragm and O ring seal. I noticed that on the bottom of the diverter valve assembly that the diaphragm assembly is bolted to, there is a small hole. It looks like a breather hole. It was damp around the hole with water "very slowly" leaking out. Will replacing the diaphragm solve this weep from this hole?
