💧 The AquaPure AP431 Inhibition Replacement Cartridge: Ultimate Water Purity Solution Review

My Rinnai instantaneous water heater added this filter to control limescale build-up. I've had it for almost 7 months now and it does what it's supposed to. I've noticed less limescale around faucets and showerheads. This is my second instantaneous water heater, the first died due to limescale build up in the heat exchanger. The plumber told me that adding an anti-limescale agent to the water heater is recommended to prevent heat transfer build-up. So far I'm happy with my new instantaneous…

I give it 5 stars although I don't know if it actually works. It's quite expensive there, so I won't buy a new one just to cut it. I cut open one that I just replaced after a year on the cold water line that powers my water heater. It is filled with small plastic balls. They have a light brown tinge. There are still a few clear ones left. Throwing them away leaves a hard part that looks spongy but isn't. That is hard. Only time will tell if it keeps deposits from damaging my water heater.

3M continues to impress me. Pretty much the deciding factor in trying this thing out was having the 3M name written on it. Any excellent reviews will also be taken into account. I have hard water where I live. He penetrates everything. Didn't want to mess with the big salt system. This system works great. After a month the limescale on my showerheads and plumbing was almost gone (it was always there). The water feels better. I have a 3 bath home with 5 active adults and a recirculating hot…

I'm afraid I'll have to reluctantly go with the naysayers on this. Replaced the cartridge which is almost 2 years old. I expected the sodium granules to run out, but when dry they were almost the same weight as a new block, with almost the same maraca sound. I'm not sure if only part of the water flow should be cleared or the entire flow. If that's all I just can't understand how I can get so much flow out of such small holes. I just can't get that much volume out of those tiny holes. I'll…

I replaced my water tank for leaks every year before I started this. Since I've been using it we haven't had a leak in 4 years, let's knock on wood. Anecdotal evidence of course, but I'd say it's worth a try if your tank keeps leaking. Before you can use it, you need an adapter. It is listed on the same page and comes with a cartridge. We installed it right in front of the hot water tank after spitting out the remaining cold water. This means less water goes through and I believe the cartridge…

I was replacing no pass hot water systems and during the process I asked the plumber to install an Aqua Pure filtration system connector just before the hot water system. I change the filter every six months as recommended. I have well water and very hard water with a lot of iron. I use the RainSoft water treatment system but it still seems like some chemicals are leaching through and I still get limescale build up. I have found that Aqua-Pure's scale inhibition really makes a difference by…
