I have two washing machines and they are placed one next to each other (this is the only way I can position them due to the space).
The first one is connected to the drain pipe under the sink normally with it's default hose and it's length (which I think is 1.5 meters or 5 feet), but the other one is placed a bit further so I needed an extension besides the default integrated hose (which like I mentioned is I think 1.5 meters), the smallest drain hose I found was yet another 1.5 meter one, so when connected it totals a bit more than 3 meters long hose (including the connecting adapter) and I was wondering how bad can this be for the washing machine, or more specifically for its pump or microorganism growth inside.
Is there anything I need to take care for or any other tips besides just finding a less lengthy hose? For a shorter hose, I think it can be found in a 1 meter variant (3.3 feet), but for that I will need to order that and maybe wait for a month to come.
Forgot to mention that due to the length, the hose curves and this is how it all looks:
