I am getting a pool that has been empty for a couple of years back in shape. The plaster was redone earlier this month and I have been limping the system along with the old cartridges that are at least 5 years old. They are a pain in the behind here in Las Vegas. It's a pain to clean four of these big guys and replacing them costs a small fortune. I am in the process of plumbing in a new sand filter, the information for which should be in my signature below.
I have a question about the design of this filter. I cannot seem to get the neck of the diffuser to swivel to one side or the other, and I have been unable to get information from Hayward on whether or not it is supposed to. The manual makes little sense, at one point saying to cover the diffuser to add the sand, but in another section they somehow expect that someone with really skinny arms can reach in and ensure that the laterals are tight.
Does anyone know if it should rotate, or come off? How about cutting into the pipe and adding a swivel of some sort?
Here is a picture of the diffuser through the top hole:
Thank you, I have already learned so much from lurking for about one month!
