Does my hole seem small ;)

So my collection pipe on my reflux had a leak so I did some pulling apart to clean it but the hole seems really small, ive read lots about people using there valve for collecting but ive only ever opened mine to full crank cause its was extremely slow. Ive attached some photos should I maybe drill it out more?.

Wow i haven't got one of those but it does look small, what is it 0.5mm hole leaving a 6.35mm pipe?
