Christopher,
Sorry about the children squabbling they get bored during the school holidays 
The best fitting to use to connect gal to PVC, when the pipe is a “Water outlet” is a fernco coupling or simular. Effectively its a high quality rubber sleave and two stainless steel worm clamps. Check with your local plumbers as in some areas these are not permitted.
Come on fellers, maybe we should be reading the questions properly ??
