Need largish prefilter for well system
Hello there!
Our water quality is terrible. Like all the bells and whistles terrible. I've got an Aquasana filter system on the way and I'm going to pick up a filter for iron but I need a decent prefilter to take out rough media so I don't ruin the more expensive filters further down in line. It's currently got a woven twine prefilter that clogs up pretty quickly so I'd like to swap it out for something that will last longer and filter more fine media than the woven twine cartridge does. I need to keep it not terribly expensive if that's at all possible.
If anyone has any suggestions, it would be greatly appreciated.
Thanks for your time!

You dont state what components your installing but they list pre-filters so you may already have one.
Big blue filter housings are what I use, they are very robust and replacement filters are about $4 each, you have to watch the cost because they add up over the years.
And, your not really treating your water just filtering it so it's not going to be a significant improvement vs a water softener, did you get it tested to see what needs to be done?

As for testing, I've waited two weeks for the water results and just can't wait any longer due to needing water to live and bathe so I'm simply planning to filter for all common issues and will add components as needed.

I'm just giving a bit of advice, depending on your water condition you cant always just filter it out!
I have iron and use a chlorine injection system to remove. You really need that water test to get the correct equipment!

If you have that much sediment coming into the system, I'd consider a settling tank. Need a mid-tank inlet, a top outlet, and bottom cleanout. Might work with a hot water heater tank, since those are designed to be have sediment drained every so often.

A settling tank is a possible option but I'd go with spin down sediment filters. Consider two filters inline / sequence. Spin down filters can be found well above typical sediment filter micron ratings - up to at least 1,000 microns - but 50 and 100 micron filters are usually enough. Spin down filters are flushed into a drain or bucket as needed. Some have an auto flush feature. They also must be washed occasionally (perhaps annually) but maintenance is far easier than most sediment filters.

Hi there Tony and thanks for the suggestion on the filter type! I did a bit of reading and am leaning towards either this one or this one. Both have good ratings so I'll do a bit more reading up on them. If you have any suggestions towards either one, that would be nifty.
Also, you say in sequence, so don't split the line put one on each line then bring them back together but instead, put one inline then put the other right behind it? I only ask because I wonder about the pressure loss the added restriction might cause. I think I understand why though if that's what you're suggesting, it's so the filter type has a second chance to pick up some of the sediments, correct?
[EDIT] or perhaps I need to bite the bullet and do a large system like this for sediment?
Thanks for all the help!

First, the backwashing filter you mention is not a sediment filter as you suspect it to be. It's for filtering backwash water. Like typical sediment filters, it's designed to filter small particles. I suggest focusing on large micron sediment filters.
In terms of alignment, I suggest a 100 micron followed by a 50 micron. From the iSpring filter you asked about:
I don't know if a single filter or dual filters are best for you but, judging from your OP, it sounds like dual filters are the way to go.
Water pressure loss is indeed a consideration. Quality filters feature low pressure loss and the overall pressure loss is minimal compared to the loss from clogging sediment.
On your choices, the iSpring is an auto flushing unit and is a good choice if you want that feature. If that's not necessary, the WSP100GR is a good option. Also, WSP100 will work well but the internal filter should be replaced every 2 years. Keep in mind filtration on all three options is approx. equal; the price difference is due to ancillary features.

Used to create a multi-layer gradient filtration system taking considerable workload off finer filters that follow it and result in a longer filter life.

Hello there guys!
Still not gotten to the filters yet but I've got some pretty great updates. First, I had a well guy come out and he found that someone had opened up the valve designed to slow the volume all the way open. This set the flow to about 10GPM but the wells here only support about 5GPM so as he explained it, it was pulling from the bottom of the well, pulling up a slurry of sand from the bottom. He closed it back down to 5GPM.
On top of that, I flushed the water heaters in both the main house and apt over the garage. While the apartment was dirty, the main house had so much muck in the bottom, it completely blocked the drain system. I had to use wires and pipe brushes to push through the mud and sand until I could get a flow of water. Well, at first it was an explosion that coated half the laundry room in mud but then we got a flow of sand and water. That took about an hour to clear out completely.
We're now able to take showers without filling the basin with sand by the time we've finished. We still won't drink it but we're chipping away at the issue a little bit at a time. Looking forward to having the filters installed. Will install the bypass and two spindown filters(100 and 50 micron) then will put the Aquasana system in after.
A little bit of moving picture magic showing the water quality from heater after about 15 minutes.
A little bit later.
