First time poster here so go easy on me I have been lurking around this site for quite sometime and it has been a huge help these past couple of years. I tried searching for a solution to my problem but could not find any answers... So here goes
I need to replace a cracked washer under the locking knob of a Hayward sta-clear c1750. Am I correct in assuming I need to remove the e-ring from the inside of the filter head hidden behind the cone in order to remove the locking knob? My concern is it looks like a pain to get the e-ring out, let alone replacing it once everything is changed as it sits in a recessed area. I usually just figure these things out as i go but figured I should ask before I can't put it back together, or worse, damage the equipment! Is there any tips or tricks to completing this? Thanks for any help or suggestions!
