Can You Remove the Filter from a Topaz, Megaflow, or Vortex?

It's a question we hear often, usually from someone whose filter keeps clogging. The short answer is yes, you can. The valve will still work without it. But it isn't recommended, and understanding why will help you decide what to do instead.

What the Filter Actually Does

Topaz, Megaflow, and Vortex are pilot-operated diaphragm valves. The filter's job is to keep debris out of the moving part of the diaphragm, where grit could cause it to stick in certain situations. It's a small part protecting the part of the valve that does the real work.

What Happens If You Remove It

Nothing stops the valve from operating. The filter isn't required for it to work, and the valve can run without one. But it then relies on your water being clean enough to run without it. If your water carries silt, sand, or mineral scale, that's exactly the water most likely to cause a sticking problem in the diaphragm.

If the Filter Keeps Clogging

A filter that plugs repeatedly is telling you something about your water. Removing it can get water flowing again, but it removes the protection rather than fixing the cause. Before you take it out, consider:

• Where is the debris coming from? Silt from a well, scale from hard water, or debris from the supply line are common sources.
• Can the supply be filtered upstream? Catching sediment before it reaches the valve spares the valve's own filter.
• Are you cleaning on a schedule? A filter that's checked and cleaned regularly usually doesn't need to be removed.

A slow-filling trough is also one of the first signs of a restricted filter, so it's worth looking there before assuming the valve itself has failed.

Keep Spares on Hand

Replacement pilot filters are available, and we recommend keeping a few in stock in case they plug up. The Topaz/Megaflow service kit and the Vortex service kit both include a fresh filter along with the diaphragm assembly, so a routine service refreshes both at once. Our guide to which service kit you need can help you pick the right one.

The Bottom Line

You can run these valves without the filter, and in a pinch it will get water moving again. For long-term reliability, though, keeping the filter in place and cleaning or replacing it is the better choice, especially if your water isn't clean.
