I've been looking for some small check valves that I need. I've been fixing the pipes at home with the water and I really need some of these valves in order to finish it. I've ordered some of them and they should arrive any moment now and then I can get to work again. I'm working as a plumber so that's why I know stuff like this and it's really handy if you're fixing stuff at home. The valves we're kind of cheap which is really good. And putting them together with the pies is not that hard so It will work out really great I think. I'm really looking forward to closing this project when the valves arrive.
