What Glue can I use to install the pipes on the rear box of the Shadow V1?

  • Use only these following solvents on the Rear Box fittings:
    • We recommend using Rectorseal® Mike 425L  as the best solvent. If that cannot be found then Standard Clear Medium PVC Cement (Sold at local hardware stores) will also work, but may cause crazing on the rear box fittings. This crazing will not affect the fittings.
  • DO NOT USE the any of the following as they can damage the Rear Box:
    • ABS TO PVC Transition cement (Teal Colored glue)
    • Purple PVC Primer. This can damage the plastics. Only use clear cleaner made for ABS plastics if needed.

**Remove from tank prior to gluing pipes to avoid damage.
**DO NOT Force Dry fitted pieces into the bottom of the rear box. This could possibly damage the overflow. Only push PVC with a chamfered edge and with PVC
Cement into the holes. ***

  1. Attach 3 short pieces (approx. 4”) of 1.5” PVC to the bottom of the rear box with above mentioned solvents.
  2. We recommend you using Rectorseal Mike 425L on outside of the rear box when gluing the PVC pipes to it. We have found that this Cement will work the best, but extreme care needs to be used when gluing to make sure the pipes do not slip out or the ports get damaged from too much force. If the proper amount of glue is used it will not take any force to push the pipes into the ports. See figure A.2 Below:
  3. We recommend that you attach 3 x 1.5” Unions to the 3 pieces you just glued into the bottom of the rear box. This will allow for easy removal of the overflow if needed in the future or for moving the overflow to another tank later.
