Nice job 👌

[@hvacmania8323]

Fantastic 🎉

[@67tr876]

Looks sick !! Nice

[@THESEASONE416]

you shouldn't install copper MIP/FIP into carbon steel fittings with out some means of separation. 6" brass nipple or a di-electric union.

[@samihabib661]

Is that megatape code in ontario?

[@Noregrets4]

Can you explain how you wire the water valve ?

[@shellogee]

Quick question. Why didn’t you use unions on both sides of the Valve?

[@RajneshPrasad-u4m]

Tell me about feed back cables

[@bb3283]

Spray it w some pb my guy, it’ll loosen that baby right off :)

[@srobeck77]

Bruh u gotta get your teflon tape more on point. Ideally u want 2-3 wraps around the threads (according to manufacturer specs; not hearsay, gossip, or any other form of non-sense logic). I counted you went around 5-6 times. Wut the heck, lol.

[@DaveArms]

That bugged me too. With new fittings, 3 layers and you're good to go
