Reliable replacement for my Hayward pool valve This Hayward SP0714T replacement valve came exactly as described and worked perfectly for my sand filter. Installation was straightforward—it matched up with the existing plumbing and fit securely without extra adjustments. The handle action feels smooth, and the diverter clicks firmly into each position, which reassures me it will last through frequent use. What I really like is that it brought my filter back to life right away. My old valve was leaking and made backwashing a hassle, but this new one sealed properly from day one. The build quality is solid, and the labeling on the top is easy to read when switching between filter, backwash, rinse, and waste. One thing to keep in mind: this is a direct replacement for Hayward sand filters, so double-check compatibility with your model before ordering. It’s also a little bulky to handle during installation, but once it’s in place it’s not going anywhere. Bottom line: A dependable OEM replacement that fixes leaks, restores proper function, and makes filter maintenance simple again.

Have been using these for many years, and makes pool care much easier.

Checked against a full taylor test kit several times. The readings are fairly accurate. This, like many products, function better if you follow the instructions. I noticed if I kept the strip in longer than a second or two the readings became a bit off. The CYA and free chlorine it tends to be the least accurate in, however, still very close. Also keep in mind, you're dealing with very close shades of colors here instead of counts of drops of chemicals, some of the inaccuracy is due to our own interpretation of the reading. Ultimately, these are great for what they are, a compliment to a proper chemical testing kit and much easier to use. I use the taylor kit to do the initial check when opening the pool, then again as I get everything where I want it. From there, I use strips daily or every few days depending on how often the pool is used. If anything seems drastically off I then go back to the taylor kit to verify. This makes the more expensive, more accurate taylor kit last much longer, while still enabling me to get a fairly accurate measurement as often as I want. The strips are an excellent time saver as well as it can take a good 10 minutes to do a proper 7 way test, where this takes mere seconds.

Very happy with these. Easy to use. Accurate readings that are easy to see. I compared them against the kit where you put the drops in and found they were spot on. I feel like the amount you get for the price is a good value.

Recommended by my local pool guy. They work great and are accurate for our saltwater pool.

Finally! A quick strip check that works…the strip colors match the bottle and we are getting accurate chemical results. So thankful to have found this.

I had a chemical service company for my pool the last 30 years. Their prices went up 3 times in the past year so I cut them loose. I used to be a certified dialysis technician so I've been approaching pool water much the same way as preparing dialysate. I tried two cheaper brands of test strips but they were very inaccurate. The colors on those were way off. These strips are much easier to read and compare colors for accuracy. I still run up to the pool store but in between their analysis, I use these and trust them. They are worth the price to eliminate guesswork.

Accuracy is very good

These are the most accurate test strips out there. I have used around 10 different brands and these are the best. The color chart is very close to what actually shows up on the strip, compared to guessing with others.

I have lost confidence in these strips. They were constantly reading very high chlorine levels which dictated how much chlorine I added to the pool but I was having recurring algae problems. I eventually bought a test that uses tablets to get a reading and that test said the chlorine levels were very low, which makes more sense. Hopefully my algae problems are now over.

Having wasted my time with swimming pool branded test strips, this are amazing! They are very accurate and even more accurate than the Jed chemical kit I have! Highly recommend!

Simple to use, saves trips to the pool shop and allows incremental seasonal adjustments of chlorinator/ sabiliser /ph & acid
