Introduction: Changing a Sand Filter Right into a Cartridge Filter

Final yr my spouse and I purchased a home with a pool we had been so excited. However all final summer season we struggled with attempt to get the swimming swimming pools water clear, it was all the time cloudy, and once I would vacuum particles would come again by means of the return jets.

After having a few pool professionals to take a look at are system the conclusion was which can be sand sort filter was to small for are system, and for them to improve it could be over a $1200. and to do it my self relying on the kind of filter it could value $600 – $800.

So after doing a little analysis I figured that I may covert our system from sand to a cartridge filter system.

Complete value of this challenge was below $165.00.

Step 1: Filter Varieties

There are Three sorts of filters Sand, Cartridge, and DE filters and every have there personal routine for regulare maintanace

Sand filters are the least costly and filter right down to 20-40 microns

Cartridge filter are of medium exspence and filter right down to round Eight microns

DE filters are the most costly and may filter to 2-Three microns

Step 2: Cruching the Numbers

After deciding that I used to be going to go together with a cartridge filter system, I now wanted to see if the the tank to my sand filter was massive sufficient and what dimension filters I can set up in it.

The within room that I needed to work with 20″ inside Dia and 17″ in hight and seven” opening.

My pool is 32000 gal. the rule of thumb is a 100 squair ft to each 10000 gal.so I would like a min of 320 sq. ft. I discovered Poolcenter.com and there sight has a bit had been you may plug in dimensions of filters. The filter that I discovered was the PLBS75 it has 75 sq. ft of filtering space and I must use a min of 5 to giving me 375 sq. ft of filtering space.

Step 3: Constructing the Hub and Exterior Risers

After eradicating all of the sand and laterals from the filter I figured that I may warmth up and soften 1″ PVC couplings and slip caps to suit over the exsiting hub as an alternative of constructing a hub from scratch.

For the laterals I glued a 2″ lengthy piece of 1″ PVC right into a 1″ slip and the opposite finish right into a feminine threaded road 90 diploma elbow. I repeated this Four occasions. For added safety I put in stainless screws on the underside aspect of the hub.

For every of the Four outdoors risers I glued two 1″ slip to male threaded ends to a 13 3/4″ 1′ pvc pipe. I drilled fourteen 3/4″ holes within the pipe. For the highest and backside caps I used 4″ furnishings sliders which have a foam pad witch seals the ends to the filter. I drilled a 7/8″ gap within the middle and eliminated a 1 1/4″ dia part of the froth . The underside cap is secured with electrical nut. I wanted it to be low profile as a result of this finish will thread into the 90 deg road elbow. The highest is secured with a 1″ threaded cap.

The final image reveals it put in contained in the tank. To put in it I needed to disassemble it and reassemble it within the tank.

Step 4: Constructing the Middle Riser and Putting in the Filters

To get the size of the middle riser I used 1 1/4″ electrical pvc conduit (I had mendacity round) slipped it into the hub that was nonetheless within the tank and simply marked it so the highest of the riser is flush with the highest of the opening. Then reduce it to that size, once more drilled fourteen 3/4″ holes (I may have drilled extra however did not see any profit, as a result of the 14 gap have a better move charge than the risers dia.). I made a cease for the filter out of a 1/2″ peace of 1 1/4″ slip coupling (tapered at one finish to seal the underside of the filter) and a 1/4″ peace of 1 1/2″ pipe glued over the coupling peace to offer it an additional shoulder. I slid it onto the riser a couple of inches up from the underside, put in it into the hub once more, slid a filter over the riser after which put in the valve physique on prime. Eliminated the valve, filter an the riser being carful to not transfer the stopper. As soon as out I marked its place I then glued it onto that spot.

Putting in the filters was fairly strait ahead. For the surface risers my first plan was to assemble them with the filters and simply screw the into place. This was problematic because of such a small opening . I needed to set up the outer risers first and angle them so I may slide the filter over them, and set up the highest caps (hand tight). The middle riser went flawlessly slip the riser into the hub, slide the filter over it, and put in an o-ring over the riser, then put in the valve and join all of the plumbing.

Step 5: Evaluation of the System

Effectively it been properly over a month and a half and it work GREAT. The pool is crystal clear. The beginning strain was at 10 psi. Its now at 15 psi so I pulled the filters they usually had been DIRTY. I anticipated them to be because the pool was de-winterized after I accomplished this mod, and it was in a determined want of a cleansing.

Sooner or later I plan on transforming the hub to accommodate 2 extra filters that can convey the filtering space to 525 sq. ft
