SEV17 and ROCOMP Filter Service Guide
Use this guide to identify the replacement filters and maintenance tasks for your SEV17 pre-filtration and ROCOMP drinking-water system. The softener requires salt replenishment, while the filter stages have their own replacement schedules. Follow the schedule for your exact equipment and confirm the current service-pack price before ordering.
Keeping track of filter replacements can be confusing, particularly when you have a whole house system outside and an undersink water filtration system in your kitchen.
To make this easier, AquaCo will send you an annual email reminder when your filters are due. You will then have up to six months from the reminder date to complete the replacement.
This page provides a clear overview of what is involved in servicing each system and the cost of the required replacement filters.
