    I'm not sure about those lines, but I have never seen them installed correctly at the manabloc, if there is one.
    They are supposed to be straight out from the manbloc and clamped within 6 inches, I think, before they go curving away to their destinations.

    While it varies depending on the brand of pipe, here is a good reference for installing Zurn's Pex. It is quite involved and very detailed.

    Of course the sink drain, tail piece, multiple slip extensions, p-too low, arm and DWV, esp. wrong primer & solvent weld PVC to ABS are wrong too - health hazard DIY plumbing.

    Mechanical joints shall be installed in accordance with the
    manufacturer’s installation instructions.

    P3003.18 Joints between different materials. Joints between
    different piping materials shall be made with a mechanical
    joint of the compression or mechanical-sealing type conforming
    to ASTM C 1173, ASTM C 1460 or ASTM C 1461. Connectors
    and adapters shall be approved for the application and
    such joints shall have an elastomeric seal conforming toASTM

    RCNYS:
    P2702 Fixture Accessories
    P2702.2 Material for tail pieces and traps. Continuous wastes, waste and overflow fittings, traps and tail pieces constructed of seamless drawn brass shall be of No. 20 gage minimum thickness.
    P2702.3 Plastic tubular fittings. Plastic tubular fittings shall conform to ASTM F409 listed in Table P2701.1

    P2703 Tail Pieces.
    P2703.1 Minimum size. Fixture tail pieces shall be not less than 1.5 inches for sinks, dishwashers, laundry tubs, bathtubs, and similar fixtures, and not less than 1.25 inches in diameter for bidets, lavatories and similar fixtures.

    Section P2704 Access to connections.
    P2704.1 General. Slip joints shall be made with an approved elastomeric gasket and shall ONLY BE INSTALLED ON THE TRAP OUTLET, TRAP INLET and WITHIN THE TRAP SEAL. Fixtures with concealed slip-joint connections shall be provided with an access panel or utility space at least 12 inches in its smallest dimmension or other approved arrangement so as to provide access to the slip connections for inspection and repair.

    Assuming RCNYS applies, otherwise similar and more restrictions if NYSPC applies. PC-NYS: Applies, Exception: Detached one-and-two family dwellings and multiple single-family dwellings (townhouses) not more than three stories in height above grade with separate means of egress and their accessory structures shall comply with the Residenial Code of New York State.

    PC-NYS:
    Ch. 7, Sec. 707 Prohibited Joints and Connections
    707.1 Prohibited joints. The following types of joints and connections shall be prohibited:
    1. Cement or concrete joints.
    2. Mastic or hot-pour bituminous joints.
    3. Joints made with fittings not approved for the specific installation.
    4.. Joints between different diameter pipes made with elastomeric rolling O-rings.
    5. Solvent-cement joints between different types of plastic pipe.
    6. Saddle-type fittings.

    Not sure what your point was RC, Are you claiming use of slip joints to extend a too-short tail-piece before the trap is allowed in NYS? Or that the use of purple primer on ABS somehow permits it to be solvent welded to PVC? (neither is allowed). There's lots wrong, as was mentioned. OP is in NYS. Can't use purple primer or solvent on ABS-to-PVC connection in NYS, period. No slip joints allowed for DIY tail-piece extensions. Trap weir has to be within code distance from fixture outlet- fixture drain junction sanitary, support at change in direction, rodent proofing, protection from physical damage, etc. etc.

    HG:

    There isn't a lick of ABS pipe in that photo.
    There's a metal worm gear style clamp on the bottom most piece that connects to an unseen pipe.

    What are you looking at?

    (And I don't think ABS is used much in NY anyway...)

    Thanks for the reply HG

    You said Purple primer was wrong.
    I posted where Purple primer is allowed.
    I do not see where there is primer/cement to join PVC to other.

    I do not see where the trap is too low.

    "Sink drain", what's wrong?
    "Tail Piece", whats wrong?

    So, since you've already gotten THAT wrong, and cannot see the obvious there is not much point in engaging YOU further.

    And yes, the white PVC is joined to black ABS with a solvent weld (and evidence of purple staining from primer at the joint) at the bottom of the opening.

    Despite Dd'A's "thinking" to the contrary, ABS was oft used for DWV in NYS.

    I see no point in "engaging" at all.
    This was not an attack against you.
    You made statements that, as I see it, are incorrect.
    I posted what I thought to be appropriate references to code.

    You act as though you are being attacked when someone says they see or understand something differently than you.

    Look again, not ABS at all. If it were primed and glued, why the need for a hubless connector? It's sloppy work, to be sure, but it's PVC connected mechanically to something else.

    I see white PVC with purple primer stain welded to black hub ABS.

    I do not see a fernco type connector.

    OP gives NYS location.
