It's always fun to have 2 minor problems going at once!
Pool light is not working. I replaced the 20 amp GFI breaker and Light switch. GFI breaker will not reset and "throws" to off every time. Any ideas what to try next?? Pool light could possibly be bad but it hasn't been use but very few hours since installation in 2009. Would a bad bulb cause the GFI to break soon as it's set??
Added DE to sand filter after deep cleaning twice and now DE is showing up on pool bottom... Multiport valve is new and I'm suspecting bad laterals but know of no way to be sure except removing sand and checking. If I remove sand I figure I might as well change laterals either way since half the work is already done. Am I on the right track with this problem??
Thanks for the help. I knew nothing of pool maintenance until I found TFP!!
