Great question. You may not need a filter at all 🤔 It depends on the quality of your water source, and the size of your zone (gpm). Based on the information you provided, you probably need a 3/4 or 1” filter. 20x30ft is only 600LF of tubing. Using the average drip line, 0.6gph x 12” spacing, that equals 6pm total.
Do you know what it plugs with? Is it plugged with dirt, minerals, rust, etc…this will help determine the filter type. And knowing the emitter flow rate will help determine the micron size.
Hi Andy, how easy should it be to remove the disc filters. I haven’t been able to remove the disc filters and I’m wondering how to remove the disc filters for cleaning?
Good question. Removing the disc filters should be fairly straightforward, but sometimes they can get a bit stuck-kinda like an old window sash that hasn’t been opened in years. First, make sure you’re turning the filter housing the correct way. If it’s still not budging, try giving it a gentle tap with a wrench or using a pair of pliers to get a better grip. Just be careful not to apply too much force, or you’ll end up with more of a renovation project than you planned-Bob Vila would tell you patience is key! Once you’ve got it loose, cleaning the filters is as simple as giving them a good rinse and reassembling. Just like working on an old farmhouse, take your time and the job will get done right.
This filter I had has two arrows in opposite directions each side. In one it's written "disk" and the other side it's written "screen". So which arrow points to the normal flow?
Hi Natanael. That is odd you have arrows pointing in the opposite direction. If you have the 3/4" size,, like the video, the filter resembles an arrow, and it points in the direction of flow. You might get a better example of this watching this video: ruclips.net/video/WzhkrF9miMk/видео.html
@@Andy_Humphrey Thank you. The right direction was indeed the same as the shape of the filter (which reassemble an arrow) like you said. Maybe the other direction (where it's written "screen") indicates the flow if it was a screen filter.
Hi Bob. Absolutely. The sediment pre filter will help remove sediment so that the disc filter is not clogged up as often and require frequent cleaning. The pre filter should cause no issues. -Andy
Hi Ernest. Pressure loss due to friction is a great question and depends on the flow rate. Each manufacture should have a friction loss chart that you can reference to find the exact pressure loss at a specific gallons per minute. Take a look at page #2 of the following link and let us know if you have any questions or need any assistance. www.netafimusa.com/bynder/A00E9BA9-E204-4E49-B393DC1328FED090-lmnfl-manual-filters.pdf
A disc filter system works best in situations where the flow can be lower to give the water time to move through the system, which is why these tend to be useful for drip irrigation systems. In a house system, you generally need more on-demand water for things like showers, dish washers, etc, that a disc filter can't keep up with, so it wouldn't be as appropriate of a filtration method in those applications.
new to Disc filters, I have drip irrigation set up in my garden with about 20 rows at 30 Ft. in length. How large of a manual disc filter do I need?

I definitely need some kind of filter. Plugs up the emitters in one season

Cool. Good to know. Have fun out there!
Can you run a sediment pre filter and then the disc filter after? (I’m running a leader 240 ecotronic pump)

Good job.. Love from India ♥
Thanks for the comment and for checking out our videos!
What did the flow rate loss and pressure loss across the filter.

Why aren't these used in houses?
