We truly value your trust in our water filtration systems and take product concerns very seriously. We would always want to clarify the cause of any isolated canister leaking and ensure you the customer has the right guidance to keep your system running safely.

Canister leaks are not the result of faulty product but rather excessive incoming water pressure or in instances hot water expansion tanks. All filter canisters are designed and tested to withstand normal residential water pressure upto 90PSI; however, if water pressure exceeds recommended levels, it can place undue stress on the housing.

Our recommendations: We strongly advise installing a pressure regulator if your homes water pressure is higher than the recommended range (typically 40-80 PSI). This not only protects your filtration system but also helps extend the life of other plumbing fixtures in your home.

Please rest assured that our products are manufactured with high quality materials and undergo rigorous quality checks. When installed with the proper pressure regulation, they provide safe, long-lasting performance.

If you have experienced an issue, our customer support team is here to help troubleshoot and provide replacement guidance. All of our systems are under a one year warranty with an available five year warranty.

Thank you for being one of our valued 25,000+ customers and allowing us to provide you with properly filtered purified, safe water for your home.

Typically, the T&P relief valve on a water heater is set to open if the water temperature exceeds 210 degrees Fahrenheit or if the pressure exceeds 150 psi. When the relief valve opens, it doesn't take much water to be expelled to reduce the pressure, maybe a cup or so. So, if you see a small amount of water in the overflow pan under the water heater, it could be that the relief valve has tripped. If the Nova canisters are only designed to handle up to 90 psi of pressure, it is very possible that a defective expansion tank can cause the canister to leak, even if you have a pressure regulator on the water supply pipe to your house. A defective expansion tank will not necessarily caused the water pressure to increase. But, what can happen is that you use all of the hot water in the tank, and then you shut off all plumbing fixtures. This causes the tank to fill up with cold water, and the water heater heats it up causing thermal expansion of the water and a huge increase in the water pressure because the water has nowhere to go. Note that older houses with one or two drippy faucets will not experience this pressure increase, or if your ice maker calls for water while the tank is heating up. Also a very high temperature setting on the water heater and a very cold water temperature will exasperate the problem.

Can you explain? Is Nova replacing the cannisters with a new version of the cannister? If they are that's a good thing and should be mentioned.

I can tell you, before all this happened, I did try to replace one of my filter cannisters with one of the Big Blue ones and it wouldn't seal properly in the Nova manifold. My guess is the Nova manifold is different and will only support a specific type of cannister/housing.

Yes, the new canisters have thicker walls at the bottom where the cracks were occurring. They have also changed the manifold where the gauges connect to brass fittings rather than plastic. The new canisters also use 2 O rings rather than one.

Thousands of us south of 44 have tankless water heaters so no expansion tanks. I wonder if we’re less likely to see canisters cracking eventually? Our Nova system is less than 3 years old, and so far it’s okay.

Thank you for your reply.
Can you tell us how big a problem this is right now?
How many customers has this affected?
Does it happen when the cartridge reaches a certain age?
Does it matter whether you have tank or tankless heaters?
What is the replacement policy/process?

Thank you.

Sorry to hear about your experience with Nova. I’m sure the Pegasus will work fine but that Pegasus analysis is a scam. Unless you had something dramatically wrong with your Nova system there is no way you should have had any sediment and or chlorine in your water especially since you were changing your filters regularly. Just curious when Nova came out to look at your leak did they do anything to fix it? Did they charge you $300 just to come out and look at the problem and left it leaking? I thought they were charging $65 for a new canister?

I could have moved on to a different supplier but I trust Nova and see no reason to change.

As for Nova. I don’t like to bash businesses and that’s not what I’m trying to do. Since I put in the system in 2021, I’ve had to call them out for leaks more than this latest time. When we decided on putting in the new system, he did some sort of temp fix for the leak just until the new system could get put in. Unfortunately, the next available appt they had was sept 30 and I’m leaving for out of state surgery on sept 25. I’d have to wait until Nov to get the new system put in so I needed to just bite the bullet and get the pagusus. It’s good Nova is obviously super busy so they won’t miss me. Lol. So yes, I guess the 283.00 was for coming out and the temp fix. No canisters were replaced and no new system. That was sort of the icing on the cake to go through with Pagusus. Reading their replies… out of the times they’ve come out to fix leaks including this time, not once did anyone question or mention water pressure.

Now that we have all the background story, you made the right decision.

I know the Pegasus system is a good system but their sales people can be very deceptive. A year ago, a neighbor was talking to a Pegasus sales person looking to buy a system and of course they asked if any neighbors were interested. I had the Pegasus sales guy come by just to help out my neighbor. So, he takes some of my water from the tap and puts some chemicals in it and tells me I have Chlorine and my water is very hard and lots of sediment. So, I then fill a glass of water from the tap and take my pool chemical test kit out and show him there is no chlorine then I took out my water hardness kit and showed him my water had zero hardness. I then explained I had the Nova three stage filter with a forth 1 micron filter stage that I added on my own and the Nova water softener. He then packed up his stuff an left without saying a word.
