Just purchased a Spring Well H20 salt based softener and combo whole house filter (CSS4) system. This isn't my first install but I do want to move things around. The house is is over 33 years old and but came pre-plumbed for a softener. The problem is it's located in the middle of the back wall which isn't in the best location.
I'd prefer to relocate the tanks to the corner which is about 16' away.
I'd also like to run another line from the new softener location to the diagonally opposite corner of the garage for a hose bib to wash the cars.
Since the house is old it was plumbed using copper pipe and I'm OK with that since I've done my share of sweating copper numerous times. I have checked into Pex but I'm not comfortable with it even though I know it's been around a long time. Given all that here are my questions.
1. Copper isn't cheap, but I've priced Type M, RDG Type M Red and RDG Type L Blue at HD and I'm trying to figure which is the most compatible with what was initially installed. Is it safe to assume when I cut apart the water loop to reconfigure it, will it reveal itself as to which was used throughout?
If I'm guesstimating correctly this is going to be pretty expensive project...
About 8 x 10' sticks of copper! The only good news is I have numerous elbows, couplings and other fittings...
2. Working from the new corner location and going back to the sink.
Is it better to extend the sink ABS 1-1/2" drain pipe across the back wall and configure an air gap at the corner location or can I run a 3/4" PVC line to the existing sink location and tie into it?
3. Do I need an additional drain P-trap located where the drain line is closest to the new corner location and can it be buried in the wall if so, do I need a utility access door?
4. Also, since the vent stack will now be much further away (about 18'-20') from the softener, will the extended distance impede the flow and if not will it be code compliant?
5. If I can extend a 3/4" PVC line horizontally (instead of lengthening the existing ABS drain to the new corner location) I hope to connect it to the sink P-trap. I found a fitting (adapter) for a kitchen sink disposal to merge a 5/8" clear poly line (supplied with the new softener) that angles into a straight section of 1-1/2" of ABS and would fit between the sink and the P-trap. Would this configuration qualify as an air gap?
I hope the way I described this isn't too confusing and really appreciate and value any input...
