Laser 250 Sand Filter - Pin Size Leak

[hallidina]

Hey. Got home to find water spraying out of my Laser 250 filter... There appears to be a few pin size holes near the label on the body of filter... I don't know how old the equipment is (got it with the house) but worked fine for last few months I was using... It was hot here in Toronto today (95 degrees) and I had filter on continuously since last night as I had added CYA in a sock (in skimmer)...

I've turned my equipment off as its quite the spray. What's the solution? Can it be patched or do I need to replace??

What is the body made of?

 

[Zadd]

I'm sure a patch job would work. Try epoxy for fiberglass. Inside the filter and out.

Wonder if it Is a sign of things to come. What is your filter pressure typically?

 

[hallidina]

I will try - how difficult a job is it to take the filter apart to get to the inside? I did a quick Google search for a manual but no luck. Pressure is typically around 15-17..

The lasers are blow molded plastic vessels, not fiberglass. I never recommend repairing a pressure vessel that is leaking, however you can do whatever you're comfortable with.

I would replace it with a larger filter. That filter is a little small for a 26,000 gallon pool.

+1 what bama said. Time for a new, larger one.

 

[hallidina]

What size filter should I be looking at? And Sand, DE or Cartridge?

 

[Bama Rambler]

Our recommendations would be a [s:3jjewtzq]200[/s:3jjewtzq] 400 sqft or larger cartridge, a 4.6 sqft sand or about a [s:3jjewtzq]36[/s:3jjewtzq] 72 sqft DE.

Was talking to the guys at Hayward and they say all I need is a sand 24" filter or 3.2 sqft ... up to a 130,000 litres (34k gallons)
What am I missing? I'm in Canada so pool only open a few months of the year...

Our recommendations would be a 200 sqft or larger cartridge, a 4.6 sqft sand or about a 36 sqft DE.

I think that should be 400 sq. ft. cartridge filter , 4.6 sq. ft. sand filter, or 72 sq. ft. DE filter as tfp recommended minimums.

From what I've learned, the manufacturers are always a little aggressive with their sizing. I'm not sure why since bigger filters cost more, but whatever. A small filter means longer run times and higher pressures. The slower you move the water through a sand filter, the better the cleaning and the less trouble with the media rupturing. Bigger is better.

You are correct! I posted before I thought!

I have a 3/4 hp pump currently... do I need to get a new pump if I go w/ the bigger filter? Leaning towards either sand or cartridge. Torn between the two.

 

[Bama Rambler]

I would opt for the cartridge in this case and you can stay with the pump you have.

If you decide on the sand, we need to know more about the pump, as I assume it's not the one in your sig.

 

[hallidina]

Hey, it is the one in my signature... but my understanding is that there is no such thing as a 1 HP filter... and that it is likely a 3/4 HP pump ( http://www.pool1.com/Motors_Uprated_Explained.asp)

 

[Bama Rambler]

There is such a thing as a 1 hp pump. If you can tell us the hp and service factor on the motor we can tell if it's a full rated ot up rated pump.

I don't think you're missing anything.

I've got the Hayward 24" filter (S244T) and a 1HP Hayward Superpump. Replaced the old Hayward 24" fibreglass filter when it failed a few years ago with the same size, now a plastic vessel, and I'm still happy with it. My pool is about 36K gallons.

A larger filter and a bigger pump may have benefits, as others have suggested, but I think the recommendation from the guys at Hayward is reasonable.

Just my 2 cents based on my experience.

My fault. HP is 1.0, SF is 1.25... so I think that makes it a 3/4 HP.
Is that enough to run the 27" or 30" Hayward Sandfilter?

Thanks! No one in my area has anything larger than the 24" in stock... so I either get that, or wait 10 days for something bigger, or buy a cartridge filter...
How you like the Hayward Pump? Not sure what you had before, but did you notice an improvement in your hydro bill? Pool cleanliness?

If it helps, I have a pretty large pool but decided on a REALLY big filter (36" - 925 lbs of sand).

I go a long time between backwashes and when I am cleaning up a mess (not that I ever have one ) it really holds a lot of debris.

I would oversize again....money well spent in my case.
