        A:  Will it’s on point with the posted Gpm. However ever if the lines are really built up it limits the process. In my case the inlet hose was swollen because of pipes constriction

          Answer This Question

          A:  Depending on your water condition. If you have hard water, you will have to descale your heater at least 2-3 times a year. If water source is coming from city supply once a year descaling is good enough. ~Team Eccotemp

                Don't waste your money
                I bought this through Eccotemp directly through one of their sales as I feel everyone needs to know about this product. - Received the delivery, item looked used or returned, opened it up and it was completely wet on the inside, contacted support for a replacement. - Received delivery on my second unit, this one looked more worse than the first one - this time it wasn't as wet but clearly used and stained from the flushing chemicals, contacted support for a return. - Received my third unit, box looked a little better but it was slightly wet on the inside but much much better condition than all previous models. Put it back in the box and waited until my next flush (the delivery and product delays caused me to call in for a service to do this so no need to this at this stage). Fast forward to my next flush and I get everything setup and start to process the EZ Flush and the hoses start to leak, contact support and ask for replacements still under warranty and once again these hoses start to leak when connected to the maintenance valve. I had to find a replacement set that didn't look like the ones that came with the unit and ended up calling for another service for the flushing. ** Be Careful of the Eccotemp solution, some of this leaked out from unit and not aware it stained my slate tiles to a lighter colour. The solution couldn't be saved and had to be recycled. Last week, I ended up needing to flush my unit and figured now was perfect, these replacement hoses did the job, and this time I learned my lesson and used white vinegar. This time no leaks from the hoses but when opened the cover while in use I noticed that none of the vinegar was recirculating. We lifted up the unit out of the basin we had it sitting in because of the last issue we had and notice the vinegar was pouring out of the bottom seams of the unit. We removed the hoses and poured everything out into the basin and as we were tilting it we could hear banging of small pieces jostling around. Cleaned the unit as best as possible, flipped it upside down while hearing all the horrible noises of something bad and removed the 4 screws on the bottom and it was a horror show of destruction. I dont know if the Eccotemp solution cause the plastics to break but this was brought to Eccotemp to rectify the solution and they refused because it was out of warranty. TL;DR - save your money and buy submersible pump kit - the construction of this EZ Flush Kit has way too many flaws for this price tag.
                  Thought it was great, turned out to be junk.
                  Purchased just over a year ago, and used it once. The one time it worked - it was awesome. Went to use it again and it absolutely leaks everywhere! Has been stored clean, dry and warm and never been dropped. Followed the directions, plug it in and walked away. Good thing I came back a few minutes later. Water - EVERYWHERE.
                    The product did what it was supposed to do and worked with no problems.

                    I used this a couple of times and now it leaks. Piece of crap!

                        Easy to use. Instructions are easy to follow. Works as advertised. I would buy again. I recommend this product.
                          Not worth buying
                          From reviews leaking after one use appears to be a common problem- I had the same experience -it renders the unit virtually useless, to say nothing about the problem of having a strong cleaning solution running everywhere. Eccotemp should be refunding.

                              Very easy to use. Way less than having a plumber come out to service the tankless heater as well. Even if you have to buy one each time it would be worth it.
