Aquatix Pro Pool Filter Pressure Gauge - Premium Spa/Pool/Aquarium Water Pressure Gauge, 2" Dial, 0-100 Psi, Bottom Mount 1/4", Compatible with Most Brands Such as Hayward, Pentair & Jandy

It works like it was made for and we are very pleased with it.

Easy installation, even for someone like me who hates trying to fix things

This gauge worked fine from June (when I bought it) until pool closing. I live in Alabama, our winters are not bad. I closed the pool end of October. So the gauge was used 4 months. Just opened the pool and gauge is completely topped out without the pool pump on. Very disappointed that I have to buy another this year.

Easy to install, but you need to add some good old white teflon tape to the pipe threads, otherwise, it slips in just a bit too easy, and you end up screwing it all the way in and it still doesn't feel 'tight'.Further, if you don't feel any resistance , you can't really stop where you want the gauge to be so you can see it easily. Your only choice is to bottom it out in the threads and it ends up where ever it ends up.All that said, it looks great, the numbers and backing are clear, so far. Who knows how long before it clouds up and /or the needle stops moving up to indicate accurate pressure? Oh well. For the price its perfect to replace a bad old gauge that stopped working!

I replaced the original Hayward pressure gauge in a Hayward sand filter with the Aquatix, but cannot get it to seat well and therefore it leaks. Washers, thread tape, etc are no help. Also, the threading in the gauge and/or filter makes the gauge install face down so you have to stand on your head to read it while it leaks. Bummer. Too late to return, will just order a Hayward
