2 min read

Replacing your valve clamp is a key step in maintaining a leak-free filtration system. In this video, we’ll walk you through removing and reinstalling the clamp that holds your multiport valve securely in place—ensuring smooth operation all season long.



Key Takeaways:

  • Learn how to safely remove the old clamp without damaging your filter.

  • See how to properly align the new C-clamp for a secure fit.

  • Discover when and why to use shutoff valves or Hayward caps to prevent water loss.


Step-by-Step Process:

  1. Turn off your pump and close your shutoff valves (or use Hayward caps in the skimmer and return).

  2. Use a screwdriver to remove the bolts from each end of the old C-clamp.

  3. Carefully lift and set aside the multiport valve.

  4. Align the new C-clamp with the valve head and tank, insert screws, and tighten securely.

  5. Confirm the multiport valve is set to the “FILTER” position before resuming operation.


Resources and Explanations:

  • Hayward C-Clamp: Secures the multiport valve to the filter tank; must be tight to prevent leaks.

  • Screwdriver: Essential tool for removing and reattaching bolts.

  • Hayward Cap or Shutoff Valves: Prevent water loss during servicing.

  • Multiport Valve: Directs water flow through various filter functions; must be reseated correctly.


FAQs:

Q1: What happens if the clamp isn’t installed properly?

A: loose or misaligned clamp can cause water to leak or disrupt filtration. Always double-check the seal.


Q2: Do I need to drain my filter before doing this?

A: No, as long as you turn off the pump and use shutoff valves or caps to block water flow, draining isn’t necessary.


Q3: How tight should the clamp screws be?

A: Tighten until both sides of the clamp meet evenly. Do not overtighten, as this can crack the clamp or tank flange.
