Are torque arrestors necessary to prevent wire fraying? I just had to replace a 3 year old pump which failed due to frayed wires, and was installed without a torque arrestor. I need help quickly:
My well pump (Sta-rite submersible 2000) failed after 2 years, 9 months and a new pump was just installed by the same pump service company, again using the Sta-rite 2000. So, same company, same pump.
The pump failed due to badly frayed wire in the well casing, per installer: "it abraided, exposing all the bare wire which shorted the pump /wrong voltage". He told me this happens fairly frequently because the tape which holds the wire gives way. It doesn't make sense to me that the longevity of a $700 pump be dependent on plastic tape but he assured me it does.
I called Sta-rite. Per the Sta-rite technical staff, the installation requires a torque arrestor to prevent movement which frays wires. The pump service company tells me they do not use these torque arrestors because they "wear out in a few years anyway and they make it difficult to pull pumps for replacement, requiring 2 men and maybe a pulling machine". When I told them what Sta-rite said, they said that just taping is standard procedure and the wire would have abraided anyway. I said that if they find the torque arrestors failed only when the pull pumps for repair, maybe the arrestor is destroyed during the pull, and in any case it may have lasted more than "a few years" especially if the pump they are pulling many years old.
The installer told me that it's just the way pump installations wear --"we deal with frayed wires all the time". Seems to me the reason for the frayed wires is the company's omission of the torque arrestor in the installation.
two questions:
1. is the torque arrestor necessary to prevent wire-fraying? or do wires get frayed in just 3 years if a torque arrestor is not used?
2. is the installing pump service company responsible for the failed pump due to wire-fraying because they did not install a torque adaptor as specified in the Sta-rite pump installation guide?
I don't want to shell out $1,000+ every 3-4 years for pumps that should provide service 10-14 years.
Kindly help me out here, soon... Philip Anderson, Monrovia MD
