PVC and VFD control
PVC and VFD control
(OP)
Hi,
We are having problems with PVC fittings installed in a water supply system. Some people said that the problem is the VFD installed, instead the cycling of the VFD system.
Anybody read or know about it? Can be true?

RE: PVC and VFD control
Can you be more specific - what kind of problems are you having? Fittings are leaking? VFD and/or pump is not maintaining stable flow or pressure?
RE: PVC and VFD control
Fittings breaks. The pressure is constant, the pump system has normal operation. It is a 7 story building.

RE: PVC and VFD control
Does the VFD kick on only when a tap is opened (water pressure drops)?
Are there anti-water-hammer devices installed on all the lines?
RE: PVC and VFD control
What is the specification for the fittings?
