Drysuit dump valve

[Jean f]

My suit is going back to dui in the next couple days for some repairs and modifications .

the questions is that on my old suit i had a low profile dump vavle on it and it did not dump properly so i replaced with the high profile valve solved the issue or not dumping . Now with my newer suit i ordered the high profile dump valve but it does not dump as fast as my old suit . should i get them to replace it with another high profile or a low profile .

Btw old suit was a cf200 newer suit tls350
