I'm in Hawkins. These filters were just under 4 years old.

I believe there was another incident with the same filter canister down the street but that was second hand info.

I think if someone does install a pressure regulator it would be good if they share what they installed, which company installed it and how much it cost so those here can benefit from the experience.

That said, I still feel the Villages water must have some way of limiting the water pressure to our homes to avoid situations like this. This is why it's important to tell us which Village you are from so we can figure out if the problem is in a specific area supplied by a specific source or not.

Nova Systems
 

Yes when they were installed I asked if it could go outside and was told That the red relief buttons needed to be covered so I covered them. When they did a filter change I was told the canisters needed to be replaced because of UV damage. So now I must change them. I had an outside water system before nova and never had this problem. I am disappointed in Nova system at this time. I also found out the time before when they changed the filters they put them in backwards.

Domestic fixtures are nominally rated to 80psi. I.e. this is the pressure they can expect to run without issue.

If you are seeing pressures well above 80, there is something else going on. I have seen pressure hitting around 100 in a home with a failed expansion tank on the water heater.

If the supply side was exceeding even 90psi, toilet valves and sinks everywhere would be failing constantly in that neighborhood.

Certain neighborhoods have a lot of pressure relief valves that start popping off between 75-80. I see these in a lot of homes off BV, north of LSL. These relief valves are in some other areas too, but practically every home up that way has them.

I am a licensed, certified and working home inspector. I get into a lot of homes. I have never found any home with a functional expansion tank where the pressure exceeded 80psi.

When Nova installs their system they always check the expansion tank if there is a tank hot water system installed but most people never do any maintenance on their until it fails, including the expansion tank. Typiclly they only last 5ish years then need to be replaced and that's if they were installed properly with the correct air pressure.

Which outdoor water system did you have installed without any problem because I haven't seen any like the Nova system with the three canisters that are rated for outdoor installation.

If that is the case, why doesn't Nova automatically install a water pressure regulator and add an additional $150 to the cost of a complete system?

I've had Nova in my garage for 3 years. No issues so far. I do my own filter changes. But if this is really an issue, seems like they should just install them universally rather than end up with angry customers.

I think this problem is relatively new and Nova is Just trying to deal with it best they can. I think if you order a new system, they will offer or ask you to get pressure regulator, but I’m not 100% sure.

I have the 3 filter system that they installed outside 4 years ago.

Or....was there a defective lot of canisters? No way to know.

If it's a "new" problem, why haven't water pressure spikes been a problem historically? Are the pressure spikes "new"? Or are the current run of canisters unable to handle the pressure like previous ones did?

Typically, a pressure regulator is a one way device that will control the incoming water pressure to the house. However, if the pressure increase is caused by a defective expansion tank, the pressure regulator will not control the pressure inside the house and at the filtration system equipment.

Yep. Which doesn't explain why this is a "new" problem. Weren't expansion tanks failing before?

When I said it was a "new" problem I meant, I hadn't heard anyone complain about it before. When I purchased my home here in the Villages four years ago, I did a lot of research on Nova and no one mentioned this problem and I've not heard anything until recently on TOTV. As I mentioned, I know they always check the expansion tank if the homeowner has one at installation but very few ever maintain that. And if it was the expansion tank causing the problem, why wouldn't we have heard about this years ago? Nova has thousands of systems installed in the Villages for 10+ years now.

My "guess" is 1) Maybe there was a shipment of canisters that were faulty. They all come from China so I'm not sure how you guarantee 100% quality. 2) Something new with our water system causing a problem with high pressures because we should not be seeing pressures that high at the water supply.

The only way to debug this is for those who can see the pressure over 80+ psi for example, they need to turn on the water in the house and then tell us what the gauge says. If the pressure only drops a little then the high pressure is coming from the supply. If it drops a lot then it's something in the home like a bad expansion tank.

This is my "guess" also. It's the most logical explanation. Occam's Razor.

I’ve had them for 4 years and never had any issues. I have my filters changed every 6 months.
