Wall fitting question

[PoolDesignnet]

Hi everybody,
The obvious answer was also the cheapest solution, remove the skimmer and brick up that unsightly hole. The kind idiot plumbed a 1.5" line beneath the now uninstalled skimmer and plugged the end with a PVC MIP plug and teflon tape. Condo Steve

Steve, I hate to say it but the obvious answer was to replace the skimmer not to eliminate it completely. And in a public pool specially. And it is not to late......

I need a place to plug in a vacuum hose. Can I unscrew the 1.5" plug and screw in a wall fitting to accept a 1.5" vacuum hose?

A cleaning fitting by Hayward W-400 or similar is what you need. It has a spring loaded cover for safety when the cleaning hose is not attached. A suction line should not be left uncovered and you are looking for trouble if you remove the plug and not use a fitting with a cover. Someone can get hurt or drown if hair or small hand and even arms get sucked into the line.
