The connection to the plastic pipe started leaking a year later. And it costs 50p.
This is taking into account that the cleaning system they supplied cost more than 2500r.
And the warranty is just one year.
So I called again before the new year and asked to do it, all the masters are busy, and they forgot.
Probably the leak can go away on its own.
I don't advise anyone to work with them.
Or order something.
