That time of year again all. Good luck all with all your maintenance and may your water be balanced crystal clear!
I recently went through a pluming overhaul. I was pushing sand and rock out the waste port. So what has been done.
1.) All filter internals replaced
2.) All filter externals replaced.
3.) All pump seals replaced
4.) All screw in fittings replaced
5.) New diverter valves
6.) Added 2 back flow preventers one for bottom and one for skimmer.
7.) Puck feeder removed and thrown out.
8.) Nature 2 removed an thrown out.
9.) Leaking bottom drain lines replaced between pump and ground level. Found what I think was a leak in a 90 seam allowing air in.
10.) Skimmer line cut and repaired where I found a leak allowing air in the line.
It has been quite a pain in the rear. However very worth it. The entire reason for this was that oer the past 10 year I have had no luck keeping prime on my pump so it has run 24x7. I should have done this a long time ago.....
I have had this noise in my multiport valve for years.... I always assumed it was air in the lines and would go away after all the work I have done.
So what is this noise and why am I still getting it. I do not remember it when we fist put the pool in. I can make it go away by turning off my main return and only send water through my slide return. Nothing else makes it go away except my filter pressure going up.
