Close the front valve of the tank filling now (A2–D2) and open the new tank’s front valve.
Overflow only runs forward, 1 → 2 → 3 → 4, so tanks before the fill tank get no new water.
Bypass the filter
Open F1 and close G1 and G2, either side of the filter. Spring water then goes around the filter into the fill header, for example while the filter is serviced.
Pick which tank fills and which supplies the cabins to see every valve’s position, or switch to the photo to find the valves on site.

Tank 2’s capacity and the 86-inch heights are approximate. Gallon type (US or Imperial) still needs confirming. Jeff · Sep 2026
The labels follow the manifold settings: tank 1 fills and tank 4 supplies the cabins, the usual setup. Each overflow only runs once its tank is full. Tank 4’s final overflow is piped to the ditch by the pumphouse. Diagram sizes are approximate. IMG_6740 · 00:53–01:58Jeff · Sep 2026
Why fill 1 and draw from 4
Water turns over through the whole chain, and drawing from one tank at a time limits how much a leak on the cabin side can drain. That isn’t a guarantee: inflow, valve settings and where the leak is all matter.
Tank 1 is the largest: the dark green, 1,500-gallon tank. Tank 2 is black, wider and shorter, at about 1,000 gallons. Tanks 3 and 4 are pale green, each 1,000 gallons and about 86 inches high.
A monitor on the manifold turns water pressure into a height for the tank supplying the cabins. Change the supply tank and the reading follows it.
Pressure sensing replaced the earlier laser sensor and worked almost flawlessly over summer 2026, according to Jeff. Tucker is up to date on the Arduino programs. Extending monitoring to all tanks and the well is under discussion.

Following a cabin branch
On this stretch the white-striped pipe is cabin water. The unstriped pipe beside it is fire water.
The line to the cabin dips and rises. When a supply tank empties, air gets in, and changing tanks hasn’t always restored flow right away; past recoveries took hours of trial and error. Bleed valves at the capped tees have been suggested.
Unconfirmed A working vent and a repeatable way to clear the air.
The branch reduces to a smaller pipe just before the cabin. Replacing that short section with larger pipe, or adding a local tank and pump, have been suggested.
Work down the list. It’s pulled together from the walkthroughs, not a tested procedure.
Check the level of the tank supplying the cabins. The monitor on the manifold measures it. Unconfirmed Where to see the reading.IMG_6737 · 00:28–01:21
If that tank is low, supply from a fuller one. See change the supply tank. Tank 4 is the usual supply.
If the tank ran dry, expect air in the line. Flow may not come back straight away after changing tanks; in the past it has taken hours of trial and error. Unconfirmed A reliable way to clear the air.IMG_6750 · 00:30–02:05
If other cabins still have water, check the shutoff on your branch. One shutoff on the walked branch serves two cabins. IMG_6752 · 00:12–00:20
If the tanks aren’t refilling, check that the fill tank’s front valve is open and the inlet filter isn’t blocked. Bypassing the filter sends the spring around it.
Drains and upkeep
Seasonal draining, and the routine checks that keep leaks visible.
Seasonal drainage
Tanks and pipes are drained before freezing weather. The newer ground-level drains carry the water down to a ditch, avoiding the flooding the old method caused. There is also a route for draining the well.
Unconfirmed Valve order, low points, and spring restart checks.
Twice a year, clear grass around the pipes, joints and valves so leaks can be seen. The lower connections under the manifold are compression fittings that loosen if the pipe is moved or twisted, so check those especially. Landscape fabric around the valve areas helps keep growth down.
The two light-coloured tanks, 3 and 4, show more growth than the darker ones. Sunlight is the suspected cause; shading or painting them has been suggested.
Chlorine tablets are added to each tank weekly to limit algae growth. The product, tablet strength and dose still need recording; algae control does not establish drinking-water safety.
Where the water starts, before it reaches the manifold.
The spring-fed wellIMG_6735 · 00:05
One source, two outlets
A natural spring slowly fills the well. The upper outlet is the overflow. A lower, submerged outlet (about 6–8 inches below the water at the time) feeds the tanks by gravity through the manifold.
The shared system does not provide potable water at the wellhead. Cabins have been advised to bring drinking water or use treatment at the cabin.
Doug and Bruce have cabin treatment systems, described as “biofilters”. Their reported water use is about 2 gallons for each gallon produced; Jeff notes that some systems can use up to 7. The equipment models and water-quality results still need recording.
