Product Description

WrekinWater supplies the Fleck 28415 Seals & Spacer Kit, a genuine Pentair Fleck wearing-parts kit covering the 2510, 2750 and 2900 valve series, ideal for a low-cost first fix when a softener starts weeping or letting hardness through and the piston itself is still in good condition.

Symptoms that mean you need this part

  • Water weeping or dripping from the valve body between the piston and the housing
  • Hardness passing through into softened water shortly after regeneration
  • A hissing or trickling sound from the valve when the softener is meant to be idle
  • Visible hardened, cracked or flattened rubber seals when the valve is opened for inspection

Why it fails / why it matters

Every seal in the valve stack is compressed between moving and static parts, and over years of cycling through wet and dry spells the rubber gradually hardens, loses its shape, and stops sealing evenly. Once that happens water finds a path around the seal rather than through the intended flow path, showing up as leaking or as hardness bypassing the resin bed.

Why buy this from WrekinWater

WrekinWater has supplied Fleck parts to more than 50,000 customers over 15 years from Bettisfield, Shropshire, and stocks Pentair Fleck alongside Autotrol, Clack, Kinetico and other major brands, so this kit is correctly matched to the 2510/2750/2900 valve series. We're UK Company No. 11000488, rated "Excellent" on Trustpilot.

How to fit it

  1. Isolate the softener at the inlet, relieve pressure, and switch to bypass mode
  2. Remove the valve cover and drive assembly to expose the piston and seal stack
  3. Slide out the piston, noting the order and orientation of each seal and spacer as they come off
  4. Clean the bore and piston thoroughly before fitting the new seals and spacers
  5. Lubricate the new seals with a silicone-based lubricant approved for potable water and fit them in the original sequence
  6. Reassemble the valve, restore the water supply, and run a manual regeneration to check for leaks

Frequently asked questions

No, this kit covers the seals and spacers only. If your piston shows grooves or wear when you inspect it, you'll need a piston assembly as well.

Yes, this kit is compatible with the 2510, 2750 and 2900 valve series. Check your valve's model plate if you're unsure which series you have.

Typically 3–5 years under normal domestic use, though water chemistry, usage volume and regeneration frequency all affect seal life.
