Cabin Water

How spring water reaches the seven cabins: through the manifold, into four storage tanks, and back out to the cabins.

Common tasks

Change the supply tank

  1. Close the rear valve of the tank supplying now: A1 for tank 4, B1 for tank 3, C1 for tank 2, D1 for tank 1.
  2. Open the rear valve of the new tank.
  3. Leave filling as it is.

If the old tank ran dry first, air in the cabin line can stop flow recovering straight away.

Change the fill tank

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.

Unconfirmed How to service the filter itself.

Send water straight to the cabins

  1. Close every tank valve: A1–D1 at the back and A2–D2 at the front.
  2. Open E1 to connect the fill header to the supply header.

The manifold

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.

Gambier manifold: tank filling, cabin supply, filter bypass, and tank bypass Spring water enters at the right and passes through the filter in section G, or around it through F, into the fill header along the front. Sections A, B, C and D connect to tanks 4, 3, 2 and 1. Their front valves fill the tanks from the fill header; their rear valves connect the tanks to the supply header along the back, which carries water to the cabins. E1 links the fill header directly to the supply header, bypassing all four tanks. The supply header passes behind F and G without joining them. The chosen settings draw the water’s path and mark every valve open or closed; they show how the manifold can be set, not how it is set right now.

The four storage tanks

Tanks 1–4 fill in an overflow chain. Select a tank to find it on the manifold.

Tank capacities and heights

1 · Big green1,500 gallonsNot recorded
2 · Black~1,000 gallonsNot recorded
3 · Pale green1,000 gallons~86 inches
4 · Pale green1,000 gallons~86 inches

Tank 2’s capacity and the 86-inch heights are approximate. Gallon type (US or Imperial) still needs confirming. Jeff · Sep 2026

Tank overflow sequenceEach tank's upper overflow feeds the lower inlet of the next: 1 to 2 to 3 to 4. Tank 4's final overflow is piped to the ditch by the pumphouse. The label under each tank shows whether the manifold settings fill it or supply the cabins from it. Tank 1 is drawn largest and tallest, tank 2 wider and shorter, and tanks 3 and 4 alike; sizes are approximate. 1Section D Filling Overflow 2Section C Overflow 3Section B Overflow 4Section A Supplying the cabins Final overflowDitch bypumphouse Tank overflow sequence 1Section D Filling 2Section C 3Section B 4Section A Supplying the cabins Ditch by pumphouse

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 · 00:53–01:58 Jeff · 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.

IMG_6740 · 00:22–00:51

Telling them apart

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.

IMG_6738 · 00:04–00:31

Reading the level

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.

Separate cabin and fire lines beside the cabinThe white-striped cabin line reaches a shared shutoff serving two cabins and a branch tee. The walked branch reaches a smaller cabin inlet pipe, a filter under the cabin, and the household. The other cabin destination is not yet traced. A separate fire line runs alongside with no connection.Cabin waterWhite stripeShared shutoffServes two cabinsSmaller cabin inletPipe reduces hereCabin filterThen into the cabinOther cabin branchNot yet tracedTeeFire line alongside · not connected to the cabin line

The branch and its shutoff

The tee takes a branch off the cabin line toward the cabin. A shutoff nearby serves two cabins.

Capped points along the lineIMG_6750 · 02:58

Air after a tank runs dry

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.

IMG_6750 · 00:30–03:40

The smaller cabin inletIMG_6753 · 00:13

A smaller pipe before the cabin

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.

The filter beneath the cabinIMG_6752 · 01:11

A filter at the cabin inlet

A cartridge filter sits under the cabin, separate from filter G at the manifold. The pipe continues from here into the cabin.

Unconfirmed How to service it.

No water at the cabin?

Work down the list. It’s pulled together from the walkthroughs, not a tested procedure.

  1. 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
  2. If that tank is low, supply from a fuller one. See change the supply tank. Tank 4 is the usual supply.
  3. 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
  4. 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
  5. 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.

Ground-level drainsIMG_6742 · 07:02

Keep the pipework clear

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.

IMG_6735 · 01:31–02:09IMG_6743 · 03:39–04:28

Inlet filter G

The manifold uses a Twist II Clean Inline Filter, 1.5 inches. Jeff is arranging a replacement O-ring from CannonWater.

Unconfirmed The installed screen rating, service steps, and whether the posted flush note applies to G. The filter under the cabin is separate.

Growth in the light tanks

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.

The spring

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.

IMG_6735 · 00:11–00:58

Drinking water

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.
