Does direct copper plumbing to the water softener valve provide enough movement for media tank expansion? My plumber direct plumbed my Fleck 5810 with copper and said that is how he installs all of them. But, I was just reading the Fleck install manual and it says the following:
Pictures of the current connections are shown below.
When pressurized, any composite tank will expand both vertically and circumferential. In order to compensate the vertical expansion, the piping connections to the valve must be flexible enough to avoid overstress on the valve and tank.
In addition, the valve and tank should not be supporting any part of the piping weight. This is hence compulsory to have the piping fixed to a rigid structure (e.g. frame, skid, wall...) so that the weight of it is not applying any stress on the valve and tank.
Do I need to add a short flex line between the copper and the valve to properly allow for this expansion or should I be fine?In addition, the valve and tank should not be supporting any part of the piping weight.
