    Hayward Heater Part rcvd is different - Replacement Part???

    Hello! Looking for Hayward Heater help.

    Pool ownership is great since switching to BBB. Thanks to this forum and everyone here. Opened it on a Sunday was looking great and passing all its tests 2 days later. Yeah!

    Can't swim though the water is only 66. Ugh! Grandkids want to swim. Started up the heater and nothing...called the repair man. It's a Hayward H100ID1. He said we needed new Hi-Low pressure switches and water pressure switch but that he couldn't get back to install them for 10 days. We decided to order and install them ourselves. How hard could it be. Ordered them online according to their diagram of the heater. Well they sent a different water pressure switch than what is in it. Found the book and it should have been part # IDXWPS1930 but they sent a CZXPRS1105. Does anyone know if this a replacement part? Will it work or do I need to send it back?

    It's hot outside and the solar blanket is not warming it up very fast.

    Any help would be appreciated.

    Is there any set point range on the two switches?

    It looks like an interchangable part but I can't find the setpoint anywhere.

    You have the correct pressure switch. The part number you have was probably changed at some point and this is the new part number.

    You can see on this web site that they list that part number they sent you. ... -s/973.htm
