Fourth part: The casing of the filter

I have to tinker it a compass to be able to plot the circles on the top of the filter that will permit to let take loud the out of the vat

Here is, the four vat pass through the panel.
A part of the casing is achieved in multiplex of 4mm

The before the filter is achieved in panel of 12mm. One fear to see to right, the two water inlets, to the over the passage for the air pipes and on the left the passage for the electric wiring.
Notice that the panel of the top of the filter overflows, because there will be achieved a small "cabinet" with the air pumps, the UV, the generator of the electric fence ...

A layer of lasure to been painted to reinforce the resistance again to the humidity of all the woodwork.
It is time to begin to bring up the things definitely: The pipes of back-wash are placed and glued, now more possible of to withdraw the vats.

A total view.
If you look well one can see the light slope of the plate of the top, there is + /- 20mm of slope.

A view him her exit for the pipe of air.

A zoom on an exit back-wash.

A small band of multiplex is placed to close the part back-wash of the filter.
The four safeblock ball valves went up and pasted.

Detail on the installation of a floodgate with a cord of silicone for the tightness to the rainwater.

Once the gone up back wash, one little to fix the panels of multiplex of 12mm to begin the base plate (not too much to fix them some time that there would be a leak!)

Installation of a moss panel with the sticky paper (always some case of leak)

One remits all straight up one full the vat with 60cm water so that they get well in place and one blocks them in position with one bomb of moss of polyuréthane.
One waits for one week for the possible leak to the level of the back wash.

After one week, one little to conduct the investment of the TEC 7 to return stem the passages of vat. A good cord of every side.
Here between two vat. Do not forget to pass slightly the plastic with emery paper and the cutback before the investment of silicone.

Inside one there of the vat.
Sometimes you see the brown and sometimes white TEC7, when I bought some the first time, there was only the blank.

To really isolate the tip of back wash, I used two again bombs of moss of polyuréthane. To place it, I drilled two holes one to right and an on the left of the floodgate to put the low-down of the bomb there and to inject the product.
In this manner, the inside of the base plate there or pass the pipes of back-wash is filled with moss, what is going to isolate the pipe and also the to block mechanically.
One can see one of the holes at the right of the floodgate, I also removed the plate of moss of the base plate for the photo. and as there is not a flight, I can fix the panel of multiplex of 12mm definitely.

A small view of one of the side of the filter that is now dressed.

A view of the side or will have the small "cabinet". The outlet pipe is also placed.
The exit is decentered because I must join a pipe that is in the concrete, it is necessary therefore that I arrive rightly over to the.

A view of the second side that is now also closed.
Not to forget to protect the brackets of the panels with the TEC7.

Here is, it is finished, more that has place it.
