It looks like you wrote: "4" SWR PIPES SS WATERTEC".
Let me break this down:

• 4" — Refers to 4-inch diameter.

• SWR PIPES — "SWR" typically means Soil, Waste, and Rainwater pipes. These are used for drainage and sewage systems.

• SS — Commonly stands for Stainless Steel.

• WATERTEC — Could be a brand name or a supplier.

Interpretation:
You're referring to 4-inch diameter Soil, Waste, and Rainwater (SWR) pipes made of Stainless Steel (SS), possibly supplied by or branded as WATERTEC.

However, traditionally SWR pipes are made from uPVC, not stainless steel. Stainless steel is rare for SWR because it's expensive. So you might either mean:

• 4" uPVC SWR pipes by Watertec, or

• 4" Stainless Steel pipes (not SWR) by Watertec, or

• Special stainless steel SWR pipes, if Watertec makes them.

Would you like me to check the specs of WATERTEC 4" SWR pipes for you? 
(If you can clarify if you meant plastic or metal pipes, I can help even better!
