White PVC inline swing check valve with compression ends vertical mount

Dayton

Dayton 4RG88 1-1/2 in PVC swing check valve compression x compression vertical mount

SKU CH-R7N3-K47GX MPN 4RG88

PVC swing check valve with inline mechanism and compression connections for vertical mounting

  • Product typeDrain Components
  • Inline swing mechanism prevents backflow in vertical runs
  • PVC body resists corrosion for general-purpose drainage
  • Compression fittings enable solder-free installation on 1-1/2 in pipe
  • Vertical mount design suits gravity-fed drain lines
  • Dayton brand reliability for plumbing system integrity

Application & Audience

This 1-1/2 inch PVC swing check valve uses compression connections for vertical mounting in general-purpose drainage systems. It suits installers who need a simple inline valve that stops backflow without requiring solvent welding or special tools.

Installation Notes

Compression fittings let you slide the valve onto pipe and tighten the nuts by hand or with standard wrenches, so no primer or cement is required. The vertical-only orientation means the hinge must face upward; mounting it horizontally will prevent the disc from seating properly and allow leakage.

Deciding Specification

The connection type is compression x compression on 1-1/2 inch pipe, so the part only fits systems built to that exact size and joint method. Buyers working with solvent-weld, threaded or larger-diameter piping will need a different valve.

Questions about this item

How can I confirm the valve is sealing properly after installation?

Run water through the line and watch for backflow when the pump stops; the inline swing mechanism should close automatically in the vertical position and prevent reverse flow.

What comes with the valve and what must I supply?

The valve body with compression ends is included; you must provide the 1-1/2 in PVC pipe, compression nuts, ferrules and any thread sealant required for the joint.

When should I choose this 4RG88 model over another size?

Select the 4RG88 when the drain line is 1-1/2 in and the installation calls for a vertical-mount, compression-by-compression PVC swing check valve.
