Question about Hayward SAND FILTER, PRO SERIES

1 Answer

A pool store installed the wrong size filter for my inground pool. It wasn't until I called for the annual filter clean that the tech told me I had the wrong size filter for my pool installed. They installed a 38 instead of a 48. So they did replace it a few months ago. I started to open the pool and was going to do the first backwash on the DE filter. The same store sold me fiber clear instead of DE powder and told me to just backwash good. I did and what a mess I have now. The filter pressure is up over 30psi and I tried backwashing it out, but the pool either sucks all the water out of the pump or runs past 30psi. The same store told me it is the spider gasket that they did not change that out and it had nothing to do with using the new powder. Does it matter and should this spider seal be replaced? Since this was the first backwash since they installed the filter I don't know what it could be that has caused this. My pool pump has not ran in 4 days and the pool is green. Help!

You just need to break the filter down and hand clean the grids inside the filter. This is something you should do once a year. As far as the water getting green you will need to get chloriene in the water. This is chemestry and the filter is just for filtering. One will effect the other but they are two different things. Green water will cause the problems in the filter you describe, So killing the alge should be done first.

Our pool is about 90000 litres of water so how big filter do we need please


If you have a above ground pool go with the Cartridge or sand, and if underground go sand or D.E. All have their ups and down you should find out what you want from them specifically cause they all do varying amounts of the same thing.

Sand Filters
(Filters using literally sand)
For sand filters, on inground pools, I like to use a 30 inch tank diameter, which is a 4.9 sq. ft. filter surface area, and holds 600 lbs of sand. For small pools (under 20,000 gals), I might advise the next size down (24 inch tank), if the budget is tight. But never go smaller than a this for an inground pool.
Cartridge Filters (like a air filter)
I have a rule of thumb for cartridge pool filters. 100 sq. ft. of filter surface area per 10,000 gals of pool water, as a minimum. I like to see the 400 sq. ft. models on inground pools above 25,000 gals. These can go an entire season without cleaning in most cases.
D.E. Filters (Ground up fossilized algae)
Because they offer the most superior type of filtration, people tend to go small with DE, and buy a 24 or 36 sq. ft. DE filter. Ugh - go Big! Nothing below a 48 sq. ft. filter, and if your pool is over 25,000 gals, go with the Big Boy - the 60 sq. ft. filter.

Also make sure the filter can take the amount of water that the pump is pushing through it.

How to Last Minute Rush an Inground Pool Vaumning


Did you ever want to just get the pool vac'd., without getting out the robot if you even have one, or pulling out the vacumn and hooking up the hoses, having to purge all the air out of the system just to get it ready.....you know the drill....and to make matters worse its real hot out!!
her's what i have found in my years of pool cleanup blunders, Put the pool selector valve to pool drain, get a long adjustable handled pole with a leaf type pool brush attachment, very slowly push the grit on the liner towrds the pool drain, do it gently and stop, wait until the smokey looking water clears(this means it went into the drain port and is being filtered out in the cannister).
Do this to the entire pool but dont rush it, after you are done check the PH and Chlorine etc. adjust, backwash the filter if your filter has a backwash system, and off you go onto another home project, this one just saved you a ton of precious time!!!
If you have the inground pool cartridge filter system you should remove the filter/filters and hose them out twice a year to keep them clear, when they start to look and act dirty and they cant get clean by hose take them to a pool pro and ask him to chemical bath them, thisfilter problem will be noticable when you see the pressure rising too high on your filter tank, it means the filter/filters are getting clooged and need attention.
Happy Homeowning!!

Question:

How do I close my pool for the season?

Step One - Debris & Chemicals
Remove any debris from pool water by use of a leaf rake attachment.
Add the appropriate amount of shock treatment to the pool water, as prescribed on the packaging.
Add the appropriate amount of algecide to the pool water, as prescribed on the packaging.
Run your filter for the appropriate time to circulate all water once.
(see your filter documentation for your size pool)
Install your floating Dispenser and winterizing tablets.

Step Two - Vacuum & Water Level
Vacuum your pool while setting your filter to the "back wash" or "waste" setting.
(this will help lower your water level)
After vacuuming, install the sump pump and drain pool to about 6 inches below your thru-the-wall skimmer.

Step Three - Parts Dissassembly & Cleaning
Disconnect all ladders, filter systems, hoses, solar reels and/or other accessories.
Using standard household cleansers, thoroughly clean all ladders, solar reels and/or other accessories.
Dissassemble filtration system.
Remove sand, cartridge or DE powder from your filtration tank.
Thoroughly clean all filter system parts.
Allow all items to dry.
Store all items in an area that will not be subject to freezing temperatures.

Step Four - Pillow & Cover Installation
Inflate all pool pillows or inner-tubes.
Install one pillow for every 15' of linear water surface.
(example: a 15' x 30' would require at least two pillows)
Tie pillows to pool area via nylon rope and place equally with respects to pool walls and each other.
(this is extremely important! This prevents freeze damage)
Install winter cover as prescribed by the covers manufacturer.

Step Five - Winter Tips
During the winter months, remove any excess snow from the winter cover.
(If you have a solid cover, this will prevent excessive weight form tearing you cover)

Hello, when i vacuum my inground pool using a hayward filter....it cleans the pool but the next day sand forms on the bottom of the pool...this was a constant problem last year....what may be causing this?...


If sand is getting back into the pool, the strainer in the filter is broken or out of place. The filter has to be disassembled, sand must be removed and the strainer must be inspected for cracks or leakage. New parts are available from most pool supply stores.

Can a person use a hayward de ec40 for either above ground pools or inground pools? if not why?


Yes as long as you are sure to match the flow rate of the pump to the filter. The biggest limit will be the low maximum flow rate the EC40 has. It will clog up to fast if installed on a larger pool...inground pools are generally larger (more gallons of water) than above ground. The pumps are more important to match as far as using inground rated units for inground pools and above ground for inground. Filters only care about flow rate and overall volume of water to keep clean.

My pool pump has a red light on it that says "insufficient water flow". My pool turned green almost over night and I'm guessing this is why. Because it's green, my filter was filthy, I cleaned most of the...


What is the pump name an model...is it fresh water or salt....is it a sand or cartridge filter system...when did you last change the filters in the pump.. is it a pump heater system.... how big is your pool....you have not said enough to have anyone diagnose your problem... If the filter has a back flush system then by all means back flush it... you need to add shock to the water like 2-3 bags(1 pound each) also before you get too crazy bring a water sample down to a pool supply store and have the water analysed, they will tell you what to use to clear up the algea. Is the water level high enough in the skimmers to feed the pump or is it low and airating?
This is both a clarification and an answer to what is going on without having a slight bit of a clue what your pool is... could be a kiddie pool 300 gallons could be an olympic 50x40 size inground with 60,000 gallons of water???? You need to tell the story, it is like me asking you if you have the touch up paint for my living room in your garage....how would you know what color is my living room....what type of paint was used...etc. etc. etc.
Write back we will get to the source.

What to do about 14 psi ?


The actual pressure depends on how clean the sand is, how well the pump is pumping, how clean the skimmer and pump baskets are. The rule of thumb would be when the filter pressure raises 8-10 psi above whatever the pressure was when you first started the filter with clean sand, clean baskets, good pump, When it reaches the 8-10 psi, it's time to backfulsh. A low pressue, with adequate return flow is what you really want. See Hayward's web site for a manual. http://www.haywardnet.com/inground/products/manuals.cfm

Do i have the right size pump for my 10,000 +/- inground pool


Bruce,
the cartridge element system you have is designed to be used for at least two seasons before needing to replace the elements. You are correct thinking that the pressure going through the filter is causing the problems with the cleaner.
if you take the elements out of the filter and see if cleaner works that will show you whether or not it is time to change the filter elements. That filter is very expensive to replace. cheaper to just change the elements.
