The title describes a thicker pressure vacuum breaker cover sized 20 inches by 16 inches, in khaki polyester, rated in its name for 5 degrees F. It is positioned for water well pumps, sprinkler valves and backflow preventers that need freeze protection, and the size spec lists a 2-way style.

Who should buy it (and who should skip it)
This cover is for homeowners and property managers who have an above-ground backflow preventer, pressure vacuum breaker, sprinkler valve or well pump fitting exposed to winter conditions. It is a practical buy if you want a ready-made insulating cover instead of wrapping pipes with foam and tape. Skip it if your device is much larger than 20 by 16 inches, is buried in a valve box, or needs a custom shape. Measure first and compare against the listing dimensions.
Before you buy the POROLIR Backflow Preventer Pipe Insulation Cover 20″X16″: quick tips
- Measure the height and width of your backflow preventer, including pipes, and compare to 20 by 16 inches.
- Check whether your device sits against a wall or free-standing, since the cover style should match the layout.
- Read how the cover closes and secures to the pipes, as a loose cover can slip off in wind.
- Look up your local rules on winterizing backflow devices, and have a plan for the cover before the first freeze.

POROLIR Backflow Preventer Pipe Insulation Cover 20″X16″ coupon & promo code FAQ
What size is this backflow preventer cover?
The listing gives 20 inches wide by 16 inches high and describes a 2-way style. Measure your device and its pipes, including any fittings, before ordering, because a cover that is too small will not close properly.
Can the INS2ZPHS code stack with a coupon?
This page shows only the INS2ZPHS code at 58% off and no clip coupon. If Amazon shows a coupon box when you visit, clip it and enter the code at checkout, then check the order summary to see what applied.
What material is the cover made from?
The specs list polyester, and the color shown is khaki. The title also describes it as a thicker cover and mentions a 5 degrees F rating. Read the full listing for the exact insulation details and fit notes.
What equipment is this cover designed for?
It is marketed for backflow preventers, pressure vacuum breakers, water well pumps and sprinkler valves that need winter freeze protection. Confirm your equipment matches the 20 by 16 inch size before ordering.
Is INS2ZPHS still working?
It was active when we last checked on Oct 31, 2026. Seller codes usually run 24–72 hours or until a set number of uses is gone, so apply it soon. Our team marks a code as ended as soon as members report it.
Is there a POROLIR Backflow Preventer Pipe Insulation Cover 20″X16″ coupon or discount code?
Yes – INS2ZPHS is the current Amazon promo code (58% off). Amazon calls it a promotion code; it works the same way as a coupon or discount code at checkout.
Do I need Amazon Prime to use it?
No. Promo codes work for any Amazon account unless the promotion box on the product page says Prime-only.
Why didn't the code apply?
Usually a different size or color than the one the code covers, a one-per-account limit, or the code sold out. See all the fixes.
