How do I know if my filter needs to be repaired or replaced?
Well, the first thing to consider is, when was the last time your filter was cleaned or serviced? This should be done every 6 months on all cartridge and DE filters. Please refer to our filter cleaning page for more details
After that, we all know that Arizona is home to some of the hottest temperatures in the United States. With that said, most pool filters are constructed of fiberglass shells that can withstand pressure readings of 50psi. Our dry heat and sun beaten summers slowly break down fiberglass. Therefore, they are a large tank just waiting to split open and spray water everywhere.
We replace close to 20 tanks per year from cracking. The change from extreme hot to the abnormally cold winter we experience once every 5 years is very common for stretching and cracking these filters.
At that time, it is a decision that you need to make:
- How old are my cartridges, grids, or sand?
- When was the last time they were replaced?
- What does the quality of my water look like?
- How efficient is my pump with my current filter?
- Should I replace the entire thing?
The answer is mostly yes! Replace the whole thing! Like every piece of equipment out there. Technology changes everything. The technology driven into pool filters today surpasses anything from the past. These are now coming NSF Certified with warranties that manufacturers can proudly stand by.
Does it matter what kind of pool filter I get?
Yes it does!There are 3 different types of pool filters for your swimming pool:
Diatomaceous earth – 1 to 3 micron filtration
Cartridge filters – 15 micron filtration
Sand – 30 micro filtration
So now I know you are probably thinking what the heck is a micron?!? Well, a micron is one millionth of a meter. I know that is pretty small but lets put that into perspective of swimming pools:
D.E. Filters are the absolute best when it comes to water quality. They filter out 1 micron in size, which means bacteria 30 times smaller than the width of your hair, CANNOT pass through your pool filter! Pretty amazing huh? There is quite a bit of work that goes with this great filter though. The maximum square foot of surface area water can pass through is 72sqft of internal surface area. That means the flow will and can be restricted when the filter is dirty. The benefit, all you have to do is backwash once a month, and then clean out the filter once every 6 months. But remember, this one needs to be “charged” with Diatomaceous Earth Powder.
Emerald Pool Service and Repair recommends D.E. Filters for most Arizona pools.
Cartridge Filters have the second best filtration on the market. At a still strong 15-micron size, they do a substantially good job filtering out the unhealthy stuff that can land into your backyard oasis. Cartridges are a really good set it and forget it (for 6 months) filter. There is no backwashing necessary. However, they do require a 6 months filter cleaning. This is the highest rated filter for teamwork with variable speed pumps due to the massive amount of square footage the filtration area has. They can go up to as large as 700sqft in residential equipment.
Sand Filters are the lowest rated filtration quality filter that is made. They do not required to be cleaned at all. All you have to do is backwash every month, and that cleans out the entire gunk that the filter has collected during the past 30 days. Although, due to our high calcium levels in Arizona, it is highly recommended that the Sand be changed in sand filters every 5 years.
Does the size of the pool filter matter?
Yes, all filters should be sized to the size of your pool. Please contact an Emerald Pools representative to make sure which filter is recommended for your swimming pool.
