Alright, last night was an easy plumbing process and the outline delineated for this build rendered out beautifully--addressed a lot of friction, heat, and bottleneck concerns.
The result was a few tricky angles with some fallback safeties to reassure maintenance, yet proper feeds and returns where they belong.
Parts:
3/4" Sch 40 Pipes - As our main line and fits snug directly hard plumbed to the Vectra M1. Schedule 80 piping was the intended solution to match the native accessories the Reefer distributed. Somewhere during ordering parts I noticed this true union ball valve in white w/ red knob and decided to cohere with the Vertex theme. Much better cadence and cleaner look imo. If you desire a glossy and less time consuming pipe to clean, select furniture grade PVC instead.
1/2" Sch 40 Pipes - Necessary to feed into the Media Reactor and adapter for the Source Line to the Calcium Reactor.
True Union Ball Valves - Very paramount for situations where it's needed to turn water off or when equipment failure ensues. It will be of tremendous help too for when the return pump needs a routine cleaning or to control flow on the Media Reactor + removal for media replenishment. Be careful when purchasing this specific item as some of them are very faulty if cheap in quality and the ballhead will pop right out once you remove the union caps--don't stint in research and finances when considering one.
Acetone - To remove prints, streaks, marks, imperfections that may be apparent on the pipes.
Oatey Clear Primer - Such a staple for most basic plumbing tasks to help prime the pipes before joining them.
Oatey Regular Clear PVC Cement - Usually, it's the good purple stuff used...but this job we wanted a very visually pleasing ReefConcept aesthetic so the choice was clear--no pun intended.
Feed Water Adapter for RO Systems - Found this handy adapter from Marine Depot and will have it wide open while 2 needle valves will be the primary precision adjustments for the effluent/drip feed--peristaltic pump may still be the best option although this works well and if done correctly, performs w/ reliable n steady performance.
A lot of work ahead. Can't wait to add sand, rock, and livestock soon. Thanks to all of you that have been following this journey thus far--truly appreciated.
