Hello! I'm building my first sump plumbing. I've built a manifold but I don't know what to put at the ends until I'm ready to install a reactor. Thanks for any feedback!
Assuming you will have gate valves on each line so if you want to gamble it wont ever leak just turn it off for that leg. I would just glue a pvc cap on until the point i needed it though just in case that gaye valve ends up with slow leak. Just have to cut the cap off when ready. The other option is direct that dead line back into sump until ready to use it.
