## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great, easy to follow instructions.
*by A***A on April 25, 2025*

The flush kit worked great, I didn’t know my tankless heater needed maintenance, followed the instructions and looks to perform pretty well. This was 5 years of buildup.

### ⭐⭐⭐⭐⭐ great descaler, just did my noritz
*by M***O on April 21, 2018*

kits a little different from the picture but it's all good, basically the same and i dont mind the container which is like a small washer tub of soap. It opens the same way, pull the plastic tab and a part of the top opens up to reveal the 2 hoses, the 1 quart of descaler, and the small pump. My pump was a small squarish pump, but it's worked great. I turned it right (theres a knob that says max and min) all the way to the right thinking i'm gonna get the max amount of pump action and it seemed to be as its pumping a lot of water right now.ok, first of all i have a noritz, and this is cake. Watch the noritz video for instructions. i think it's on youtube, just look for noritz flushing.right now it's pumping away, in the first 10 minutes, my clear water turned from clear to a weird blueish color, i'm assuming it's all the mineral build up. The descaler must be some sort of mild acid as i used my finger to punch the top and it felt a little like it was burning a few minutes later, so i washed it. You just let it run for an hour. oh and yeah, you leave the noritz heater plugged in and on, so whatever temp setting it was, you will see it will turn to a blinking 11. Just ignore it and finish the hour of descaling. After that dump that stuff down the toilet and wash out the bucket. Now you can leave on the hot water hose in the bucket and just turn on the cold water by removing the cold water hose, and closing that valve, then opening the main cold water valve to flush any left over sediment. This was easier then i thought and will try to do this once a year now. Noritz recommends 3-4 gallons of just white distilled vinegar, which is a non toxic mild acid, but this descaler works great too. I will buy this descaler once a year now and hope the pump and hoses last a few years at least.But 5 stars because overall, was easy. It looks daunting in the beginning but it was pretty easy. great kit!Oh and the kit does have 3 rubber washers, if you look close, the hot water hose only has one connector so make sure you use that one for hot and stick the rubber washer inside the connectors. The cold side of course connects to the pump and the cold valve connector so you need both washers on that hose. That way they wont leak, and seriously i had no leaks. Yes, the parts are cheap in the kit but once you know what the parts are, make you own kit.

### ⭐⭐⭐⭐⭐ ... RTGH-95 series tankless hot water heater (TWH) with the recommended Rheem RTG20220AB valve kit about 15 months ago
*by C***L on February 11, 2016*

I purchased from Amazon and installed a Rheem RTGH-95 series tankless hot water heater (TWH) with the recommended Rheem RTG20220AB valve kit about 15 months ago. Although the TWH has worked perfectly with only an occasional cleaning of the prefilter, recently the water flow has slightly decreased with a concomitant decrease in water temperature. Since my water is somewhat hard, descaling seemed like a possible solution. The general descaling procedure supplied by Rheem recommends the use of many gallons of neat food-grade white vinegar. So I looked for alternatives.I purchased this Whitlam system based on reviews, price and convenience. The system arrived with a bucket very different from the one pictured on Amazon. It is rectangular, white with a fixed lid. Removing the blue plastic strip, released the lip flap. Before mixing the Flow-Aide concentrate, it was necessary to remove small pieces of the blue plastic strip that had fallen into the bucket. The pump came with a black coarse foam prefilter over a plastic insert that slipped over the pump input. I would strongly suggest sliding off the foam portion of the prefilter, leaving only the insert to prevent the end of the return hose from clogging the pump intake. I did not and, after completing the descale solution flush, there was a significant amount of small pieces of the black foam in the used descale solution. The TWH prefilter also contained pieces of foam. Even if you remove the foam filter before use, I suggest checking the TWH prefilter before returning you TWH to full service in case particles from another source have been introduced.I should mention that the dilute Flow-Aide is initially a cloudy yellowish brown. I my case, within a few minutes, it changed, becoming increasingly light blue and more clear. At the end, the used solution was clear with a slight blue tint. Although not mentioned in the product literature, I am assuming that this indicates that my TWH contained scale and the descale was successful. Although the Rheem user guide for my TWH only recommends descaling to increase water flow, not water temperature, my water temperature is now noticeably higher.Other reviews for this and similar systems offered by Amazon correctly note that this type of system can be more cheaply fabricated from individual parts. Since I had multiple submersible pumps, extra washing machine hoses and plastic buckets, alI I really needed was the Flow-Aide concentrate. However, I use my pumps for other things and would need to alter the fittings and carefully clean them before descaling. To me, the convenience of having a dedicated system housed in a small plastic bucket stored next to my TWH was worth the additional cost.
