^THIS^
Regardless of the one year warranty, Nova isn't a $20 item. We're talking about a ~$700 system which clearly has enough issues that multiple people on here are complaining about it.

I don't have an exact number of system issues it has been isolated out of 25,000+ installs

Both, more issues with tank systems due to bad expansions tanks on them (not our product)
when we do filter changes our tech's do a quick tap/sound check to tell if it full of water.
They also check for any abnormalities in the system.

The water system in TV is not pressure regulated at each home like other municipalities, they are designed with different size pipes in the street to in theory control pressure.

We have personally seen pressures over 100 =120 psi at times in different villages.

These pressure spikes also effect the rest of the plumbing in your home, the under cabinet water hoses, washing machine etc

We recommend adding a pressure regulating valve on the incoming water pipe.

Replacement policy is 100% first year and and optional 5 year extended plan

1. The plumbing systems for potable water essentially form a closed piping section subject to heating at the water heater. The liquid expansion increases pressure in that enclosed section but the pressure reducing valve does NOTHING to reduce the water pressure in the closed section. The check valve at the water meter prevents any water flow back to the system. The high pressure just makes the pressure regulating valve close more thereby further eliminating liquid volume out to the distribution.
2 Based on extensive work on piping systems, the only relief device required would be a small thermal relief valve. Releasing about 2 quarts of water would reduce the pressure buildup of raising 50 gal of water some 50F degrees ( 70 to 120F for example). This heat up would take several hours so the release is drip, drip. This is what we used in any closed section of piping. If the liquid were hazardous such as gasoline, the TRV would release the gasoline around enough block valves until it was at the inlet of the storage tank and the backpressure was the liquid height in the storage tank.

Rather than speculate what the pressures are for the water systems, I suggest that Nova contact Jacobs Engineering to explore what the current controls are for the systems and what the measured pressures have been. I volunteer to participate if both parties agree. I can explain to both organizations what my experience/expertise has been.

AS to failures, I have had 2 canister failures and a reverse osmosis failure and a leak.

As to Pegasis, I talked to them and politely asked them to leave when they asked for glass of water and poured lemon juice in it (citric acid) and created a foaming mess which they described as bad stuff in the raw water. I told them I passed high school chemistry and all they did was acidify the natural bicarbonate in the water and turned the CO2 free. Reverse antacid.

The failures seem to be pinholes which are manufacturing defects in my estimation. A one year warranty on a water system is inadequate. I bought a new system after 8 years. Hopefully it works for 10 years.

I defended Nova in the past. Hopefully I can do it in the future.

Just like a long list of other items, stuff doesn’t do well in the intense heat found in Florida garages for several months each year. Oh well, a small price to pay to have to shovel nothing but sunshine during the winter.
