Plumbing screw up? Or is it ok?

So I may have screwed up my drain plumbing. Please see the pics. The first pic shows how it was supposed to be, and the second shows what I did. Should have been paying attention. To fix it will be a pain as it's all cemented in place. THe holes are in the side to allow water to flow and get over the air pocket of the U correct? And the tube up top is to control the flow right? Will it work the way I did it?

The way it's supposed to be...


The way I did it...


Help please.

 

I would just redo it.. PVC is pretty cheap..

 

drill a new hole where it was supposed to be?

 

I think it's fine, it's just a siphon break, you will need a hole in the top like in the first pic though to allow some air to get into it when it's running.

 

I would agree, but it's cemented all the way down through the bulkhead and into the union. I can't take it out without pretty well having to redo it all.

 

I will plug the hole and redrill a new one, and insert the straw thingie through the new hole.

Now I understand it's a siphon break. I though it was to allow the tube to flood with the trapped air in the U, but now that I think about it, it would flood without it too since it's not really a completely sealed system.

Thankfully I can save it. I was getting worried.

thanks for the help

 

Sounds good, one thing for future use is that any plumbing inside the tank/overflow area does not need to be cemented, since it's all going to be wet anyway it doesn't have to be completely sealed, it makes no difference.

 

Amen on that!!!

One thing to keep in mind is NEVER glue the standpipes together in your OF. You WILL have to take that out some time in the future to clean it. You can bet on it. Just push them together and they will be fine.

 

You know what, that makes all the sense in the world, now that I've glued it all. lol. What about the return plumbing? I'm assuming that would have to be cemented because of the pressure right?

 

Yes, the return needs to be cemented, and any drain plumbing that is outside the tank needs to be cemented. If you still have the option I would look at sawing off the standpipes you have and getting a slip by thread bulkhead that way you don't have to cement anything to the bulkhead which makes maintenance a million times easier.
