In my opinion, there is a lot of information in Google and, if you wish, you can find everything you want in it, even a diagram of your device. I personally do not fully understand what you are talking about, but as I understand the topic is related to water and that it is not connected to your device. In my opinion, the best solution, if you have problems with the water pipe, then you need to contact a plumber service. So that you do not accidentally aggravate anything, it is better to call professionals, for example, the commercial plumbing Vallejo service who can solve your problem for you. It is not worth the risk and hope that the problem will be solved by ourselves. Also, not every person can answer correctly, there can always be different conditions and perhaps the person says the correct answer, but his problem was slightly different and may not coincide with yours. So be careful.
