Compool solar diverter valve cracked. Replacment part is pentair 270094 but it's not truly compatible. I know Pentair bought compool. Anyway, it doesnt sit right in the housing and water can slip by. the end that is inserted is much shorter and needs to almost go in further. I'll add a picture (OEM on top, left insert is much longer than the replacment on bottom left insert). Does anyone have solutions or has run across this before? Need the drain down feature.
