Default Water filters.

Filter systems for your lake or island property. Getting frustrated with having to change my filter weekly. Have just one filter for my system and wondering if there is something else I can install for better filtration. Any recommendations?

Why do you have to change it weekly?...Is it because of sand, silt, etc, etc, clogging it up? If so you need to look at where your water intake is and move it or put it up on a stand so its not sucking in sand.

As an fyi... I could go all summer without changing filters. I have two, a 5 micron and a 50 micron. My intake is in 9' of water and on a stand...

I'm with Dan--if you have to change weekly, you have some sort of fundamental problem that a filter cannot solve.

Sundancer,

I see a lot of islanders with their water intakes right next to the rocks on their breakwater in 2 or 3 feet of water. Nothing could be worse! This area Is usually the warmest because of the rocks being warmed up by the sun which also causes algae growth where bacteria will and does grow. This area is also the most stirred up causing issues with filters. Water intakes really need to be in the deepest Calmest water possible away from breakwaters.

Dan

My line runs under the dock to about 25-30 feet out..sits in 4’ of water elevated on a crate. Doesn’t sit on the bottom and water fairly calm. Seems like it’s the typical winni brown stain on the filters when they clog up...no sediment or silt..
I am ordering new type filter to try.

My line runs about 65 feet out and sits about 2 feet off the bottom in about 15 feet of water. I have the charcoal filter, sediment filter, and UV chamber and that brings it to drinking quality water. I replace the filters and the UV light once a year, every spring.

This is a link to the system I have: https://www.freshwatersystems.com/pr...SABEgLT5PD_BwE


The bigger filters cost a lot more so I left the old small filter in place before the new system when I installed it. The small sediment filters are about $5 at Lowes and I change them every couple of weeks. I figured if they caught 80% of what came in it would make the big filters last all season. So far so good. It has worked well for about 5 years.

Arrow "Maintained" Lawns Grow Algae...

I've been filtering from the tap. Only two gallons of lake water will clog a coffee filter!

I suspect filaments of dead algae.

(Water intake is 4-feet off the bottom in 8-feet of water).

Depending on how your filter is made, you can just rinse it off.

The most practical suggestion though is likely where you were advised to locate the intake to where it isn't laying in sand. A simple way to do that is to tie it to a cinder block. It may take a couple tries to get it to land with the intake on the "up" side.

Default Test?

Our intake is in about 8-10 feet of water and probably 80' from shore, on the non traffic side of the breakwater. Periodically we send a sample of tap water to a lab (Granite State Analytics, they'll mail you a kit) and the test results are good quality water with a small amount of bacteria, so we use it unfiltered, as we have for many decades. A couple of years ago, my daughter installed a reverse osmosis system that feeds a separate tap in the kitchen and the fridge ice maker. She's happy, and it doesn't take up space like bottled water or a filtering pitcher in the fridge.
1. Move your intake to deeper less disturbed area
2. Get it tested before you spend a lot on new filter systems.
3. I recommend a well pump that stays in the lake year round instead of messing with a jet pump that is noisy and has to be routinely replaced at inconvenient times.

Red face Check Later in the Season...

Your filter's clogging may be temporary:
The lake level is still high, so wave and wake action is still pulling soil, silt, and debris from the "high-water" level. (Out from under shoreline rocks).

'Course, algae levels will increase, but that's for later...
