I am having a bit of a difficulty here with this pan-connector set-up. It is leaking slightly from the joint where the p-c on the WC connects into the elbow p-c. Would it be better to replace the elbow p-c with a single socket bend like this with a new p-c (as existing) on the back of the WC. Alternatively would it be worth considering replacement elbow p-c & straight p-c and loading the joint between the p-c’s with silicone sealant?
