Watts 790409 – Frequently Asked Questions
1) Will Watts 790409 Whiteline polypropylene pipe fit standard 1-1/2 inch Schedule 80 fittings?
The outside diameter is 1.90 inches on a nominal 1-1/2 inch pipe size, which is the standard iron pipe size OD for 1-1/2 inch, so it mates with fittings built to that OD. Wall thickness is 0.20 inches. Confirm the fitting is the matching polypropylene socket-fusion or Whiteline system component rather than a PVC solvent-weld fitting, since polypropylene is joined by fusion, not glue.
2) What material is Watts 790409 pipe, and what is it used for?
It is polypropylene (PPI), part of the Watts Whiteline high purity process piping line. Polypropylene is used where the fluid has to stay clean or where the line carries chemicals that attack metal or PVC, typical of lab, deionized water, and process waste applications rather than general potable supply.
3) How long is each stick of Watts 790409 pipe?
Each length is 10 feet of 1-1/2 inch Schedule 80 Whiteline polypropylene. Plan your takeoff in 10 foot increments and allow for fusion joints at each coupling, since cut ends have to be rejoined rather than glued.
4) Is Schedule 80 polypropylene the right choice over PVC for a lab drain or chemical waste line?
Polypropylene is the usual pick when the waste stream includes acids, solvents, or hot discharge that would degrade PVC, and the Whiteline PPI pipe is built for that high purity process duty. PVC is cheaper and solvent-welds quickly, so it stays the practical choice on ordinary cold drainage and general service where chemical attack is not a concern.
5) What is the inside diameter of the Watts 790409 1-1/2 inch Schedule 80 pipe?
Working from the published 1.90 inch OD and 0.20 inch wall, the bore comes to roughly 1.50 inches. Use that figure when you are checking flow rate or whether a probe or tubing bundle will pass through the run.
6) What Watts part number do I order for 1-1/2 inch Whiteline polypropylene pipe?
Order Watts 790409. That number covers the 1-1/2 inch Schedule 80 Whiteline PP high purity process pipe in a 10 foot length, and it is the single model for that size and schedule combination.
