  • Need help w/ plumbing stuff....

    I wanted to try and get some plumbing order for my new tank.

    i want to order something where i can disconnect the PVC from my dart pumps if needed.

    I was looking at some ball valves with i think you call them unions on each end but those are like 25 bucks each i need 6 1.5" ones and 4 2" ones the 2" ones are like 30!

    so can i skip the ones with ball valves and get get i guess unions so i can disconnect my plumbing if needed?

    i will have 1 ball valve on the out put of my return dart just incase i need the flow turned down alittle.

    anyway let me know!

    thanks guys!

      I would go ahead and use the true union ball valves on all your pumps. It makes it so much easier to disconnect and clean them when you need to.

      I don't think that they will restrict the flow at all.

          He is correct Nick. True Union Ball Valves are the way to go I just ordered some monday for my tanks. I too am using Darts

                Nope ... no worries.

                so can i skip the ones with ball valves and get get i guess unions so i can disconnect my plumbing if needed?
                Generally speaking, I prefer to have ball valves on BOTH sides of the union ... this configuration allows me to completely isolate the union (... and mindless convenience has always seemed to me to be worth a few extra bucks). If a side of the union drains automatically when the pump is off, then you don't need a ball valve on that side. BUT ... if there's still any water in the line, and you don't have a ball valve ... well ...

                ... have plenty of towels on hand ...

                i will have 1 ball valve on the out put of my return dart just incase i need the flow turned down alittle.
                Always a good thing ...

                ... HTH
