Your pictures of this Sight glass looks to be longer than wants current install on my filter valve assembly see attached picture. Also your picture of sight glass appears to have hole in the end of sight glass , want prevents water from spraying out during backwash ?


A  Answered on 10/8/2021 by InyoPools Product Specialist Rich N.

Hi Calvin, no worries. There is not a hole on this sight glass - it is just the way the mold was designed and the way it was photographed, and it is not the correct sight glass for your Pentair - Pac Fab Top Mount valve 27-2526 anyway.  You would need this Sight Glass - E-17-S1 and the Sight Glass Gasket - E-16-S1.

I need what appears to be a 1.25 diameter site glass for a 40 year old Hayward pool filter multiport.

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.

I need to replace the sight glass on my Haywood Pro Series - S220T, can I do it myself? Do you have an instruction video? Thanks, Selena

A  Answered on 9/5/2019 by InyoPools Product Specialist Lennox H.

Hi, Selena. Replacing the sight glass is something that you can do yourself. We do not have a video, the sight glass simply unscrews from the valve body.

These sight glasses are threaded to the port in the valve so I would recommend holding it with a hand towel as you loosen.

I'm installing my pump for the first time myself. I have everything pretty much done except for the sight glass SPX0710MA and the gasket that came with it. Does the gasket go around the sight glass or in where the sight glass screws in at?

A  Answered on 5/29/2018 by InyoPools Product Specialist Hector F.

These gaskets sit inside of the port where the sight glass threads into so the glass actually compresses against it.

I am looking for a sight glass with a screw in the middle of it

A  Answered on 8/5/2016 by InyoPools Product Specialist Lennox H.

Hi Tim, We will need to know the model  of the valve that you have in order to locate the correct sight glass. The current slight glasses does not have  a screw but threads.

I have an old Haywood SP715 and the sight glass is much shorter than shown here. Cannot install a long sight glass due to interference with the coupling nut of main line. Is the short sight glass still available?

A  Answered on 7/17/2016 by InyoPools Product Specialist Lennox H.

Hi, Unfortunately, this is the current sight glass used on all Hayward multiport valve.

The sight glass does not fill with water when filtering. It does when backwashing. It always used to fill when running...

A  Answered on 7/5/2016 by InyoPools Product Specialist Lennox H.

Hi Jim, The sight glass is only filled with water when in "Backwash" mode.

Looking for a replacement sight glass (glass NOT plastic) for a Hayward Pro Series Sand Filter Model#S244T. Do you have this part? Thanks

A  Answered on 5/6/2015 by InyoPools Product Specialist Brian M.

This is the part number that matches to the site glass for that Multi-port valve. SPX0710MA I know that it once was glass, but I believe they have now switched to plastic. To be 100% sure, may I suggest giving Hayward Tech a call at 908-355-7995.
