Opening The Tank On A Pentair Clean And Clear Plus Pool Filter

HOW TO: Clean Your POOL FILTER (Pentair)

The Pentair Clean and Clear Plus ranges from 240 square feet to 520 square feet. The only difference between the sizes is the height of the outside body which directly correlates with the length of the cartridges inside. So, splitting the tank on each will be exactly the same. While going through the filter, its a good idea to give everything a thorough inspection to make sure things are working right. Dont worry, Ill explain how.

  • Barrel Nut and Tension Spring Assembly: you will need a 3/4-inch socket or wrench to loosen and completely remove the barrel nut and tension spring assembly. Make sure to take note of which washers are in what order.
  • Band Clamp: Remove the band clamp from the circumference of the filter. Be careful, the clamp likes to jump off and fall.
  • Tank Lid: Lift the lid up and over the top of the cartridges inside. Be cautious not to lift the tank top from the air bleeder and pressure gauge assembly as it can break quite easily. Once the lid is completely off set it to the side to be inspected and cleaned.

Now you will see the four cartridges that need to be cleaned. If this is your first time doing this, you may want to take a quick picture of how the assembly looks all put together. As you look everything over, the four cartridges should be vertical, the top manifold should be tight, and the center tube and breather screen should be intact.

Simple Effective Low Maintenance Filters

Sand filters are one of the most popular ways to filter water. For good reason. They are simple, effective, and require very little attention. Pool water is routed through a sand-filled pressure vessel. Over time, dirt accumulates in the spaces between the sand particles causing the pressure in the vessel to rise as water finds it harder to pass through. This signals you to backwash the filter. Simply reverse the water flow and knock out the dirt.

  • You may also fix this problem by using different or more powerful pool cleaning chemicals.

High Pressure In Filters

Pentair Clean and Clear Plus Cartridge Filter CCP420 ...

Can affect diatomaceous earth filters, but is more common with sand filters.


Check the pressure gauge of your filter system. High pressure means pool filter problem. To know the standard pressure of your pool filter system, go through its manual.


Pressure in the filter is jointly maintained by the pump, water levels, and filter media. If anyone of this is not working correctly, it affects filter pressure. This problem can also occur if your pool filters are very dirty and need an in-depth cleaning. A lot of debris and contaminants baking up in your filter media can lead to serious pressure issues.


  • Turn off your filter and perform a backwash.
  • Check your filter thoroughly for any damage.
  • Replace the damaged piece if you find one. If you do not find any damage, replace your filter media with a fresh

When To Replace Your Filter Cartridges

So when do you replace your filters? There is no expiration date, so its important to know signs of a cartridge that needs replacement.

Lets start with the bands. Contrary to what you may have heard, those bands are not wear bands. This means that the cartridge does not need to be replaced at the first sign of a broken band. However, the bands will break down over time. If you see a significant amount of breakage on the bands, look closely at the cartridge to ensure it is still in good condition. Those bands are specifically designed to ensure proper spacing between the pleats of the filter, so if the bands do break, your filtering ability will be diminished.

Next, look at the coloration of the cartridge. It will never be as white as when you bought it, but it should not have permanent dark brown or oily stains. If it does, that means it is saturated with oils. You need to soak it in a cartridge cleaner to help pull those oils out. If the oils wont come out with a good cartridge cleaner solution, you may need to replace that cartridge.

PRO TIP: It is not a good idea to use any sort of acid dilution on a filter cartridge.

Now, look between the pleats. You dont need to check them all, but check enough to get a good understanding of whether or not the material is starting to fray or come apart. If the material is visibly degrading, you should consider replacing that cartridge immediately because you are no longer getting proper filtration.

How To Clean Pool Filters

The pool filter is one of the most important pieces of equipment. Without the filter, your pool would essentially become a swamp after a few short weeks. As the water circulates, the water passes through the filter media either Sand, Diatomaceous Earth, or Cartridges. This filtration media is designed to catch small particles and debris to prevent them from being redistributed to the swimming pool. After a few months or so, the filter becomes clogged and backed up with that debris which prevents the water from passing through the filter media. This is a sign that it is time to clean the filter. Below we’ll break down the procedures for cleaning each filter media and the signs to look for that could indicate that the media needs to be replaced:

    How to Clean a Pentair Quad DE Pool Filter, aka Diatomaceous Earth Filter

    5 out of5 stars on 4 ratings

    The Pentair/Sta-Rite System 2 Mod D.E. Filter’s unique design provides two major advantages over traditional-style D.E. filters: its single cartridge style module replaces the more complicated multi-grid assemblies that are difficult to clean and reassemble and its unique balanced-flow tank design maximizes the use of the modules surface area to trap more dirt and reduce the frequency of cleaning. This guide shows you how to clean a Sta-Rite System 2 Mod D.E. Filter. As water flows through the D.E. coated folds of this cartridge filter, the folds will become clogged, water will not flow thru the filter as easily, and pressure within the filter will increase. Operationally, with water flow down, you will not be turning you pool water as frequently and your pool decontaminates will start to build up. It’s time to clean your filter. As a general rule of thumb, your filter should be clean at least once a month during the summer and every other month if running in the winter.&

    Inspecting A Pentair Clean And Clear Plus Filter Before Tear Down And Cleaning

    Before I go tearing into any filter, I like to take stock of what Im working with. So lets first point out all the parts as you approach the filter tank. A lot of folks like to go from top to bottom, but in this case I want to go from the bottom up.

    Each of these units has a tank base which consists of the bottom tank of the filter canister. Near the bottom of the tank there is a drain plug along with its O-ring. Moving up from there are the inlet and outlet bulkhead fittings that have the plumbing running through them with union style connections, along with each O-ring. Holding the two halves together is a metal clamp band with one barrel nut tension spring assembly, early models may have two barrel nut assemblies. Moving up from there you will have the tank lid or top half of the canister. Attached to the top of the tank lid is a pressure gauge assembly with a combined pressure relief valve.

    Its important to take a mental picture, or a literal picture, of the positioning of each of the movable parts prior to opening everything up, because if one thing is wrong dangerous things can take place.

    This protects the pool from corrosion or scale buildup. Using a water test kit, adjust the water to the recommended levels of pH, total alkalinity, calcium and chlorination.

    If you want to add a winterization chemical kit, do it now. These kits put high levels of chlorine and algaecide in the water to prepare it for the winter months ahead. Your pool retailer offers ready-made kits for the purpose use according to the maker’s directions. In the case of larger pools, you may be directed to supplement the kit with additional quantities of some chemicals, too.

    Your Final Freeze Insurance: The Flotation Device

    Before you put on the cover, you’ll want to install a flotation device in the center of the pool. This device needn’t be anything fancyit can be a “pillow” sold at your local pool retailer or a truck innertube. The float balances the rainwater and ice sure to form on your pool’s cover over the winter. Even more important, it eases pressure on the pool walls by allowing winter’s ice to push in on the flotation device, not outward on the walls.

    No Water In The Pipes = No Freeze Damage

    Unscrew and loosen any quick-disconnect fittings or unions at your pump and filter system, then blow out the pipes. A wet-dry shop vacuum or air compressor is ideal for this. Force the air from your pump down the skimmer and through the skimmer pipes.

    Blow out the return plumbing by hooking up your compressor to the return lines at the filter system, or by screwing it into the pump’s drain plug. Keep at it until you see air bubbles emerge from the return jets, then tightly plug the fitting below the water line. Close up all exposed pipes with plugs.

    Also blow out the main drain line . No diving necessary to plug up the drain pipewhen you see bubbles coming out of the drain, plug the pipe on your end or close the gate valve. This will create an “air lock” in the line, ensuring that no more water can enter it from the pool side, which protects the main drain line.
