I have a old swim quip aluminum filter. The backflow valve is worn. It is made out of brass and I'm unable to get parts for it. Will this work?

Hi, Could you send us a few photos of your filter to include a photo of the label on your filter tank, your filter valve, and a wide-shot of the complete filter and valve? To supply photos simply click the reply link below and upload your photos. Once we get those photos we can make the proper recommendation.

When using a slide valve on a DE filter. What position should I put the valve to empty the pool? As there are only two positions, can I only use Normal and Backwash, then place it in Backwash to empty the pool? Thanks for the info

Hi. Using a slide, the backwash position will double as waste.
