Little things like this are what need to be taught on KZread, you see lots of people showing off their systems and letting you watch them dig and place cinder blocks, but it’s the ideas and theory that people need to learn for building their own systems.

A very small hole drilled a few inches above the clean out would keep you from having to drain the system and only require removal of debris

To be completely honest, If I had my time again, I'd probably invest in the float mechanism and build the rest myself; or come up with a better homemade solution than the one I did a video on.

I was going to do something similar with a smaller container prior to going into the first cistern, but I like this idea as well. I think I'll do a combination, but I definitely will install a minimum of two of your cleanouts first, and a series of filters; not just one. I will also install a small petcock at the bottom of each barrel to drain anything that may still make it through. While this is for my garden, I also want this as a backup water supply in the event of SHTF.

Such a great explanation. I am being entrusted by The Black Pearl Network to work on this project in West Papua. This is very helpful. Thanks

The length of the sediment collection pipe should be corresponding to the area of your roof. A bigger roof needs a longer pipe. I would advise on installing a tap out of the lower section of the sediment pipe (right before the final 'basket") so you can drain the contaminated water with a hose instead of having 10-20 liters of water splashing on your pants every time you clean it.

Good vid. On the first flush system, make the fill connection to the storage tank with a wye fitting rather than a tee. I found that larger, heavier debris may not make it off the roof right away in a light rain, only to be rinsed down after the first flush pipe is full. This makes it a straight path to the storage tank. By using a wye fitting, the debris has to travel up hill for a short distance, where if it's heavier than water it drops back down into the first flush leg

The heavy debris doesn't bother me much, mostly pine needles, the mozzie net/mesh deals with that. The first flush setup is mostly to stop dust from the roof flowing in and sludge building up in the tank in my case. I live rural with a dirt road 100ish m away in a pretty dry area so it is a big problem. Our rain water collection is our primary source of house water. The clearer the tank the easier job the filters have.

Awesome thanks ❤

Just saw one of these in youtube shorts but he had a hose connected under the silt collection cap. A small section of sponge hose or the type that leaches water to flower beds would allow the lower section to slowly empty itself so you would not need to empty the silt collector after each rainfall.

Nice!

Very informative vid. I'm in the process of building my own rain harvesting system and I had the idea of using a clear 5 gallon water jug as the first flush. 8' of 4" PVC has a volume of 5.2 gallons. Using the water jug lets me see inside, saves space and saves money as you can find empty jugs for free. I picked up 2 empty jugs. I'm just having trouble with fittings and looking for some insight and ideas.

A problem with this design is the the water rush will still create a very muddy mix. I'd suggest a method to slow the water down then a buoyant object to block the water after the flush fills up to allow the rest of the water to divert to the tank.

Great video, very informative! In addition to a first flush setup, what are your thoughts on filtering the rainwater from a roof with modern asphalt shingles if you wanted to drink it, shower with it, etc.?

To be honest, I know nothing about asphalt shingles; we don't really use them here in Australia, so I don't know enough about them to even make an educated assumption. I know there are some really good filtration systems out there that I would consider looking into. On my system, we have one filter for all the water going into the house, and another one (finer) under the sink that has a dedicated spout up on the sink that we use for drinking water. That's what I would look into.

tanks come with a hole for an overflow pipe. you can pipe this into an existing soakwell or drain. but very importantly, the exit pipe must be capable of the same amount of outgoing water as incoming so it should never overflow out the very top.

Potentially. Watch part II to see what I did with the cap. Maybe you can do something similar or replace the cap.

Get a tank with a drain in the bottom. Every time you open the valve, it gets flushed.

Where is the ball and why you don't need it ?

Problem with this is that the drain pipe will always fill up so subsequently all the water coming after the drain has filled up will just drain into the tank regardless of the drain this is becouse water will always rush into the inlet pipe

Won't the dirt just float back up and into the rain barrel once the 'Flush system' is full?

First flush (dirty roof wash) is denser than the fresher rainwater. As such, it quickly settles to the bottom of the diverter. If you drain a fixed quantity first flush diverter, the initial water will smell but as the water column drains, the water quality will improve substantially. First flush diverters with drippers can easily lose 4-6 litres per hour.

I think the turbulence in the pipe would let stuff flow throw. Dried bird poop might float out. I think it will work to some extent, some sort of simple filter would work as good.

Just so you know, we don't call it a plain T👍😂🇺🇸

I see two problems with this system right away. THis is not a true First Flush system because there is nothing inside of it to prevent any floating debris from coming back out of the well area and going back into your storage tanks. Secondly, the First Flush systems are designed to leak water out the bottom of the well area slowly so the tank can drain between rain showers on its own. If the tank does not empty and the next rain comes the water from the roof then bypasses the system altogether and goes straight in your storage tank. When I built my system I used multiple 4 inch PVC pipes as the well area so that I can collect the first 40 gallons before the water goes to my storage tanks. At the top of my First Flush system, I used a 4" to 3" adapter. Inside the main 4" pipe I placed a white plastic Whiffle Ball which floats on the water and as the water in the tubes rise goes up the 4" pipe and then gets stopped by the 3" adapter sealing the dirty water below and diverting the now clean water to my storage tanks. At the bottom of the 4" pipes, I used threaded plugs that do NOT have an o-ring and I do not have tightened all the way up. This way the water can slowly leak out to reset the system after the rain stops.
