Have purchased a home with an inground pool equipped with a Triton sand filter. The filter has functioned well for several years and been backwashed, as required.
My question is whether the sand in these filters needs occasional additional quantities due to backwashing losses and/or whether the sand needs to be changed entirely on some schedule. The user manual for this equipment seems quite rudimentary and mentions nothing about maintaining/changing the sand, other than backwashing. Also, I can find no web site for the manufacturer, just a blizzard of store sites selling the equipment.
Can anyone out there provide some guidance? and a link to a manufacturer web site?
Thanks.
