    Pump On / Pump Off Pool Test Service

    Pool losing water, but not sure when? Our Pump-On/Pump-Off test helps diagnose plumbing leaks by isolating whether your pool loses water when the equipment is on or off. We provide this advanced leak detection method throughout NJ with quick, accurate results. There are 3 areas a pool can leak:

    1. A pressure side leak in pool plumbing lines (the returns)
    2. A suction side leak in pool plumbing lines (skimmers and bottom drains)
    3. A non-plumbing pool leak (pool liner, pool light, skimmer mouths, around penetrations, etc.)

    When doing the following tests, keep in mind that the pump CANNOT be running if the water goes below the skimmer. Also, do not do either test when it rains.

    Pump On / Pump Off Test Steps:

    1. Fill the pool to its normal level (halfway up the skimmer or tile)
    2. Make an accurate mark on the pool where the water is filled to (duct tape on the skimmer plate or tile would work)
    3. Turn the pump OFF for 24 hrs.
    4. After 24 hrs., check to see if the water level went down from your tape mark. If so, take pictures of the tape to document the loss.
    5. If there is a loss, re-fill the pool to the original tape mark.
    6. Turn the pump ON for 24 hrs.
    7. After 24 hrs., check to see if the water level went down from your tape mark. If so, take pictures of the tape to document the loss.

    Just be sure that you do the 2nd test (pump on) for the same exact amount of time you did the pump off test. If you can do it for the same time period (i.e. 7pm to 7pm) – that would be ideal. Try to do each test for 24 hours if possible.

    • If the pool leaks faster (or only) when the pump is ON, this can be an indication the leak is in the pressure side of the pool plumbing
    • If the pool leaks faster (or only) when the pump is OFF, this can be an indication the leak is in the suction side of the pool plumbing
    • If the pool loses the same amount of water both on and off, then more often the leak is likely non-plumbing related

    Will M.Will M. ★★★★★ Our home inspector, Knox Home Inspections, recommended Randy, and I’m so happy that they did. Atlantic Pool Inspections has great reviews, and I can see why. It was a very busy time of the year for closing down pools, and Randy managed to find a way to squeeze us in, and we are very appreciative of that. Randy is very experienced and took the time to teach us about our first pool. Randy also checked the whole property around the pool, including the gates and all the equipment. He got us the report fast, and it was very detailed. We are really happy we picked Randy to do the inspection and would recommend his company to anyone.Response from the ownerWas my pleasure to help. Enjoy your new home and pool! Here’s to a happy and healthy holiday and new year! Saad D.Saad D. ★★★★★ I had a leak in my pool, and Randy from Atlantic Pool Leak Detection came out and found the issue quickly using his equipment and by diving into the pool. He located the leak in a short time and patched it right away, which completely stopped the problem. I was very happy with his professionalism, skills, and overall service. Highly recommended!Response from the ownerGlad to help. That water was VERY COLD - but we got it done. Can't let the pool leak over the winter. Have a great holiday and new year! Bob SBob S ★★★★★ Very Impressive. Atlantic Pool Leak Detection was able to narrow down the pool plumbing underground leak to a 3 foot diameter. After digging down 30” or so, I found the water. Fixing the pipe isn’t as easy as it seems, but Randy has a company he recommends to do the underground work. Worth every dime. What a relief! Thank you for your excellent service.Response from the ownerGlad to help! Yes - Pavel is great at the underground repairs and does terrific work. You can finally stop adding water to your pool. Have a great winter!! Julie M.Julie M. ★★★★★ I had a fantastic experience with Atlantic. They were efficient, thorough and great about communicating! I would give them more than 5 stars if I could!!Response from the ownerRyan and I were glad to help. Have a great fall/winter!!!!! Rama R.Rama R. ★★★★★ ⸻I had an excellent experience with this pool leak detection company. They were prompt, professional, and used advanced electronic equipment to carefully investigate the issue with my liner. Before starting, they took the time to review everything we had already tried, which I really appreciated. Their search was thorough and exhaustive—they initially found two tiny leaks that couldn’t fully explain the water loss, but they didn’t stop there. They maintained clear communication, gave us instructions, and returned for a follow-up evaluation at no extra charge. That’s when they finally discovered the true source of the problem: a leak below the skimmer.What stood out most was their commitment, sincerity, and pleasant demeanor—qualities that are rare to find these days. Their persistence and competence ultimately solved a frustrating problem, and I am truly grateful for their outstanding service. I highly recommend them to anyone in need of pool leak detection.Response from the ownerThank you so much for your kind words. Ryan and I were glad to help! Have a great fall/winter!!!! Cathy F.Cathy F. ★★★★★ Randy and Ryan are timely, efficient, kind and extremely knowledgeable. I highly recommend you contact them in the event you believe your pool may be leaking water.Response from the ownerRyan and I were glad to help - have a great fall/winter. Richard SRichard S ★★★★★ I had the pleasure of using (Atlantic Pool Leak Detection & Pool Inspections) for a issue/leak in our 16x32 inground pool. I rarely use the word pleasure, when talking about a contractor. However in this case it was. Randy and Ryan came out, and again explained the procedure. They meticulously went through their protocol for detecting the leak location. Several minor (non leak) issues were found and corrected. The main leak was discovered and corrected. Randy kept in touch, the following few days to confirm the leak issue was corrected. My only issue is, I would love Randy/Ryan to drop the leak detection business, and start a kitchen renovation company. If you should be, unfortunate and have a swimming pool leak, I highly recommend, Randy and Ryan).Thanks againRichardResponse from the ownerThank you for the review. Ryan and I were glad to help!! Sam M.Sam M. ★★★★★ Stephen B.Stephen B. ★★★★★ Randy was extremely helpful in helping me navigate the world of leak detection and repair.

Erin K.Erin K. ★★★★★ We tried a few other places to fix our pool (indoor) water loss issue and no one was able to fix it. He is usually booked for weeks but it is so worth the wait as he works with you to do testing before he comes out so you don’t waste money/time for testing. He was able to identify the source of the problem and fixed it right away! He is so knowledgeable and is truly the best in class. I would have been able to enjoy the pool more over the years if I had gone to Randy in the first place! If you have a pool water loss issue, I strongly recommend you reach out to Randy!!Response from the ownerErin- glad to help! Now you can turn the autofill off and just enjoy your pool.
