Editing this review after some months. The seller immediately replaced this item and the replacement is working fine. Still only 3 stars because the design is lacking but working for now.
After trying two of these I can say that the part is junk. The plastic weld gives out after 2 weeks and the sealing portion of the valve is ejected from the assembly body and into the pool. Then the water is then free to flow out the top and will not reach the polaris. I must question the source of this part. I will be looking for an another source for an official Polaris part.
To make matters worse the return policy for Pool Supply Warehouse allows replacement only. I do not want another valve that fails and will not pay for return shipping. Keep your junk, not spending any more money on this lost cause.

Not Real Polaris Product, Broke in First Week2017年8月24日 - 已在美国亚马逊上发表
My original Polaris pressure relief valve lasted about 6 years, so I felt confident in ordering another. When I received this it was apparent that it was not manufactured by Polaris, and it lasted exactly one week before I found the black part and spring in the bottom of my pool with water streaming from the outlet. The manufacturing process was poor and the inner cage part completely separated from the outer button head and shaft. I returned the product and am still waiting for my refund. Don't buy this!
Improved Performance2019年7月31日 - 已在美国亚马逊上发表
My pool is 12 years so I've had to replace and/or rebuild just about everything. The polaris was moving a bit sluggish even after a rebuild (my second). I went ahead and replaced this after reading some reviews that indicated that it would result in improved performance. I can't remember the last time I did so I'm thinking it's been at least 5 years on the current relief valve. After replacement I saw an immediately improvement. The polaris cleans the pool in half the time, much faster and more efficient. Pleased with the purchase.
Lifesaver!2016年5月25日 - 已在美国亚马逊上发表
So glad I purchased this. My little Polaris 280 cleaning buddy was sad, and slow. And the old pressure relief valve was letting out way too much water. I wasn't sure if the cleaner/hose was clogged or if the spring in this valve was worn out. Turns out it was definitely the spring. Now he's back to cruising around the pool, climbing the walls, and accidentally spraying the kids with his tail!
Polaris Branded Replacement Part - Problem Solved2018年5月1日 - 已在美国亚马逊上发表
This is a Polaris brand replacement, not a knock-off. Simple to replace and solved the small leak that had developed. After 15 years in chlorinated water, most plastics will break-down, and the black valve seal had cracked and was bleeding a small bit of pressure causing my 380 to not operate at peak efficiency. After replacing, it was running around the pool like it was new. Shipping was quick, and no issues with packaging.
