How to remove whole house filter

The bypass busted on this Dupont whole house filter so I bought an identical replacement for it. Went to change it out and realized when I spin the unit around the threads it loosens on one side but tightens on the other side.

Decided to leave it for now, Unfortunately I must of shredded the plumbers tape enough that I'm leaking out both outlet and inlet as marked in picture. So now I want it off but can't figure out how to do it Plumbing is not my strong suit, but I'm very motivated to do it myself!

As mentioned I already have an identical replacement ready to go, just need some guidance on how to remove the old unit and screw on the new one.

Any tips, tricks, tools I need would be MUCH appreciated.

Remove the black insulation from the pipes and pull out further and post another picture.

You'll need to go back a place where you can open the system up.

There's a isolation valve before the filter, the red one, and one you can't see traveling up the wall after the bib. The yellow you see is the makeup water shutoff for the boiler.

Hard to say with the black covering still over the pipe but if you have copper.... it may need to be cut to get a starting point.

Yes, it's all copper. What part of the insulation do you want me to remove? I don't understand why any of the copper would have to be cut. All the fittings connecting the water filter are threaded.

Yes.... the fittings are all threaded..... in the same direction.

You will have to cut the copper pipe at the red line. Unscrew that valve from the filter. Unscrew the filter.

Gotcha, I see what your saying. Later I'll take the rest of the insulation off and see where the person who replaced the old water filter did his cut (used to be an older one in the same spot) my guess somewhere by the pressure tank. Had him upgrade it when he replaced the pressure tank a few years ago.

I would recommend adding a union somewhere in the run as you're replacing it. The union would allow you to start unscrewing parts of it without having to cut the piping.

It looks like a nice setup otherwise though! Your guy did a good job using brass fittings (as opposed to galvanized, which are cheaper, but will rust through in 10-20 years.)
