Doesn't matter

When you're trying to open the housing, did you make sure to relieve the pressure by turning on the cold water faucet handle, so no water comes out, after shutting off the cold water valve? I ask because without doing this step, you've got around 1,000 pounds of pressure applied to the system, which would be impossible for anyone to loosen! The rubber dish glove is a very good suggestion. It's also definitely helpful to have a towel to catch any water spilling from the housing (as the housing is full of water)! You can also try the method shown in this video: kzbin.info/www/bejne/q3fNqX13rtOrhJY I hope this helps! Thank you for using Hydroviv!

Some people do have two systems, one for hot, and one for cold. In most cases, having one on the cold water side is sufficient, as the water you drink should be dispensed from the cold water side, and not the hot water side. Our Founder and Chief Scientist explains it in this video: kzbin.infoWlhepNQjNyo

You will want to let the water run continuously for at least 3 minutes.

All of our filters are specifically tailored to the water chemistry in the locations that they are going to be installed. Each order that comes in is assessed by our science team, where they look up the water data for the area specified by the order, and the filtration media blend that's needed is determined from there, and the filters are then built to order. The filters currently stocked and sold by Amazon are "one-size fits all."

What is the order number or email you used to place the order with us? I'm trying to have our Support Team assist you and obviously if you just can't install the filter, we need to try to work out a return. However, we can't help if we are not able to look up your order or account.

I'm very sorry for the difficulties you've been having. Please contact our Support Team at [email protected] for troubleshooting and further assistance.

I ask because without doing this step, you've got around 1,000 pounds of pressure applied to the system, which would be impossible for anyone to loosen! If you've done that and still can't loosen it, we have a video showing a quick way of making it easier to loosen, which you can watch here: kzbin.info/www/bejne/q3fNqX13rtOrhJY You can also wrap a hot, damp towel around the lid for 3-5 minutes before you begin.

If you have hard water, depending on how hard it is, you may not need to treat it. If you do want to treat it, you can use a water softener. Or if you want to remove the minerals, a Reverse Osmosis system will do that. However, in this case, the cloudy water has nothing to do with the mineral content in the water. If you watch the video, you'll see that the water contains dissolved air (which happens when there's air in the line or pressure in the system, like when it is first installed). The bubbles rise up to the top and dissipate, leaving you with a clear glass of water in just a couple minutes.

The optimization process for our drinking water systems is based on your shipping address. When we get an order, our Water Nerds: 1. Analyze millions of water quality measurements from local, county, state, federal, academic, and our own test database. 2. Cross-reference these data with the latest toxicology thresholds (not outdated regulatory limits). 3. Select filtration media that fixes the problems found in your water (dirty secret: not all types of filtration media work in all types of water). 4. Build a customized filtration system that is specifically optimized for the problems with your water.

We'd love to see your test results! You can email us at [email protected] and let them know you want your data forwarded to the Science Team. Thanks!

We keep your filter formulation on file for future shipments of replacement cartridges. In addition, we also do a check on your water quality data every time you order a new replacement cartridge in case anything changes in your water between shipments, and update the formulation as needed.

We have your zip code on your account (that already has your address, zip code, formulation) so we don't need to ask for the information again. Obviously, if something has changed (such as if you've moved and are at a different address) between filter changes, you will need to let us know so we can update your formulation appropriately.

We have extensive data on contaminants found in the water, so we are able to build our filter formulations in a way that are robust enough to cover minor differences (such as different neighborhoods using the same water system or even cities with similar water chemistry). In addition, we are proactive when we formulate a filter, so we include specific contaminant removal media if we have good reason to believe it's in the water, even if it's not specifically reported by the municipal water companies, to ensure that you're covered!

We match your filter formulation to your water chemistry. We have a proprietary algorithm that we use where we prioritize contaminants to build the formulation. We check to make sure your water chemistry has not changed before your replacement cartridge is sent out. Obviously if there are any changes, or if you have moved, we will need that information from you to make sure we update your formulation to match the water chemistry at your new location.

We're very sorry you're having difficulties. I have included some tips below for opening the system. Tips for opening the system: ◽️Double-check that you have shut off the cold water supply under your sink. ◽️Turn on the cold water faucet so that all the water can drain out of the cold water line. (This releases the pressure inside the housing. If you don't release the pressure inside the housing, there will be several thousands pounds of pressure inside the housing making it impossible to open). ◽️Remove the system from the mounting screws if it is mounted on your cabinet wall. ◽️Make sure that you are using the blue wrench. ◽️Slide the blue wrench all the way up the housing. You can also wrap a hot, damp towel around the lid for 3-5 minutes before you begin.

Follow instructions on the bleach bottle. Or here's info from the CDC with guidelines. Hope this helps! www.cdc.gov/hygiene/about/cleaning-and-disinfecting-with-bleach.html

Unfortunately it's not just poop. The problem is industrial runoff, much of which has contained PFAS, and this industrial waste gets mixed into the poop and so the whole mixture gets contaminated. Then they process it into "biosolids" but the PFAS and other chemicals in the runoff remains, (the processing does not remove toxic contaminants). When this is then spread onto the farmland, it contaminates the soil and consequently the crops grown on it. Also, because of how soluble PFAS is, it can seep down from the soil into the ground and contaminate the water sources below (like the groundwater aquifers). If it was only poop, it wouldn't be such a big deal. The problem is that they mix that with all the other waste products including the chemical waste, creating a dangerous and toxic mixture that does more harm than good.

If you have the ability to have a dedicated filtered water spout installed jn your kitchen, you can absolutely hook the Hydroviv up to the dedicated faucet using an upstream splitter (available on our website).

I'm not sure what you mean -- is water not coming through the filter? Please contact our Support Team at [email protected] so they can help you troubleshoot your issue.

Yes! Many people living in apartments choose Hydroviv because no drilling is needed and they can uninstall the filter and take it with them when they move. However, we always advise you to make sure you get approval from apartment management or your Super before installing.

@@WaterNerdTV okay. Thank you (:

We show the installation on the cold water line because that's the side most people use for their water for drinking and cooking. The hot water would not be filtered unless you have a separate filter for the hot water line as well. If you're drinking or cooking with the water, we urge you to use the cold water side and heat up the water separately if you need it hot. I have been doing this ever since a chef at a cooking school told us that this was what he always did (he NEVER cooked with water coming from the hot side). Even municipal water companies suggest this, mostly because there's usually a lot of buildup and residue that collects in the hot water heater, and you don't want that in the water you're consuming. For installation, you could install a separate system on your hot water line. Some of our staff (personally) use one on the hot water side and have no issues.

@@WaterNerdTV I get the drinking water/using cold water for cooking, but washing hands?? And for us that water plants, which we consume, is not filtered. I guess if you want a garden, or also want your hot water filtered, id have to get a whole house water filtration system.

Your question may be best answered by sending photos of what you're seeing. Please contact the Support Team at [email protected] for installation assistance.

Ours gets stuck every time. We don't over-tighten and use silicone in the threads. Tired of fighting the battle.

@@jooleepadoolie I shall remember that for next time. Thanks

I'm so sorry for the difficulties you've been having. We appreciate your feedback, and I'm passing your comments onto the product design team. Make sure you relieve the pressure inside the housing by turning on the cold water faucet handle, so no water comes out, after shutting off the cold water valve. If you don't release the pressure inside the housing, you've got around 1,000 pounds of pressure applied to the system, which would be impossible for anyone to loosen!

@@WaterNerdTV Yes, I did all of that. I was finally able to unscrew the top after much swearing, and several comments here. i am dreading the next time I have to change the filter. I also had to screw the top on very tightly so that it didn't leak, so I'm sure next change will be no picnic either.

Well, I finally got the thing opened, and put in the new filter. Now I'm having the opposite problem - I can't get it tight enough such that it doesn't leak. There should be a gasket on the thing so that you don't have to be Hercules to tighten the top.

If you've done that and still can't loosen it, we have this video showing a quick way of making it easier to loosen, which you can watch below. To remove the plastic tube, you need to push down on the top ring around the opening (both sides) and simultaneously pull out the tube. Pushing down the ring releases the clamps holding the plastic tube in place. You can also wrap a hot, damp towel around the lid for 3-5 minutes before you begin.

@@WaterNerdTV Yes I did turn on the faucet. It was still nearly impossible to open the thing.

For reliable and accurate water testing you need to send your water samples to a certified water testing lab. That's unfortunately the only way for you to get accurate reliable data. We wish there was an easier, less costly way to do it but these rapid tests just aren't accurate enough to provide meaningful or useful information.
