DE Grids with holes or other damage can be replaced individually, or you can buy the entire grid set. Grids can also be crushed if you store them in the garage during winter, from an SUV! You can usually find holes in grids by hosing them clean and inspecting throroughly. Chemical damage can burn holes through the fabric, or a severe water hammer effect can crush grids. A loose grid assembly, with the thru-bolts not fully tightened, or from incorrectly spaced grids, can allow DE powder to bypass through small holes where the grid inserts into the manifold. Over time, DE grids will develop small holes in the fabric, or the stitching on the grids can begin to unravel. A common cause of DE in the pool is a missing or damaged manifold air bleeder ‘sock’ or ‘screen’, which are used as strainers for the air bleeder on top of the manifold.

Manifolds can also crack if the grid assembly falls over hard while it’s out of the filter tank being cleaned.

The manifold had cracked around the air bleeder assembly, probably from running too long at high pressure, or a return side valve could have been closed, causing a water hammer effect to crack the plastic. In the video, Rob replaces the DE filter manifold on cousin Joe’s Pentair DE pool filter. Water leaking out of the backwash port while the valve is in the filter position, would indicate a need for a new spider gasket, or piston o-rings, if you have a push-pull slide valve.ĭE POWDER LEAKING INTO POOL DE leaking from Manifold If your valve is leaking, either around the lid, around the handle, or where the pipes come in and out of the valve, there is probably a need for some valve parts (not considered filter parts). The filter valve on a DE filter is unique, and different from side mounted sand filter valves. Squirt in while open, then unthread the pressure gauge. Super glue can sometimes effectively repair this little crack. If the assembly is cracked around the pressure gauge, this is usually caused by having years of Teflon tape built up on the gauge, expanding and cracking the plastic housing. If it drips water, there is usually an o-ring that is missing from the air relief stem. It’s an important safety measure to open it before turning the filter pump back on. The air bleeder on top of the filter tank (sometimes automatic, sometimes manual), is meant to release air from the tank during start-up. Using a pool lube will prevent it from dry rotting, and can help in sealing up a leaking drain plug. Some DE filters also have a large o-ring on the drain plug. The drain plug for your filter tank should be wrapped 3x with Teflon tape (wrap the threads in a clockwise direction). If it still leaks, inspect the o-ring and clamp band or filter tank halves for damage. This tapping will help to seat the clamp over the tank halves. Tighten up again, using the handle of the socket wrench, or other heavy tool, to tap the clamp band around the edges, as you tighten. If the clamp band leaks, shut off the pump right away, loosen and reposition the clamp band.
When tightening your clamp band, make sure it’s centered over both tank halves, and tighten the clamp with a socket wrench, until the springs touch. Start with a clean and lubed belly band o-ring. Let’s take a look at some common DE pool filter repairs, all of which you can do yourself, with the help of our pool filter parts. A DE filter is so good that it can actually prevent water problems from occuring, or when required, can clean up adverse water conditions in 12-24 hours. So, they have more parts, and some extra steps for the filter operator, but it’s a valid trade-off in my mind.
They are also more complicated in operation, requiring the operator to maintain the ‘cake’ of filter powder on the grids, and flush out the grids with a hose at least once per year. This is due to their more complicated design, with twice the number of internal parts as compared to sand or cartridge. filters have an ugly side – they require a little more maintenance than sand or cartridge filters. The human eye can’t even see particles that are below about 35 microns!īut D.E. filters can filter down to a ridiculously small particle size, about 2 microns. There is no better type of pool filter to have working to keep your water clean and healthy. If you have a Diatomaceous Earth (DE) pool filter, congratulations.
