Cabin water system: the big idea

Posted on Updated on

The first project combines relative ease of completion and maximum lifestyle improvement. I don’t mind hauling water but a supply of running water will later, on the addition of the photovoltaic system, facilitate the addition of running hot and cold water both to the sink and the outdoor shower.

A 275 gal. (1140 l.) IBC tote in palletized aluminum frame. 330 gal. (1249 l.) is another standard size.

Running hot water you say? At a remote cabin you say? That’s the plan. The reason I have to wait until I add solar power is the location of my water reservoir –a 275 gal. IBC tote used once to transport non-GMO organic fructose syrup to a cannabis edible manufacturer– in its preferred location will only generate 6.495 PSI. Manufacturer’s specs for most of the instant propane water heaters I’ve seen requires a minimum 20 PSI for safe operation. A 12v inline kicker pump –drawing electricity only when in operation– will solve my PSI problem without wrecking my battery levels.

There is really no levelling or prep required at the tank site. My landlord Alban’s aesthetic sense for the land insists that the tank be conclealed from view so once installed it will receive ‘the Treebeard Treatment’ (to wit, a layer of chicken wire with moss and ferns intertwined into it). I want to keep the water temperature as low as air temperatures will allow so I’ll probably overdo this step and use some opaque gardener’s plastic as an underlayment to the Treebearding, which will have the twin effect of obscuring any high-albedo bits of white plastic or aluminum that might otherwise give lie to my efforts at concealment.

water system flow chartOutflow adapters with valves are commercially available to replace the rudimentary valves included with IBC totes so to save time and guarantee durability I’ll invest in one of these new. These adapters are usually threaded for standard ¾” garden hose so I’ll purchase a lead-free adapter to fit the PEX I intend to use as my main outflow to the house and eventually to the 12v kicker pump once the solar power is in. I am considering purchasing a length of used, discarded fire hose to use as sheathing for the main PEX water line. I worry about rodents more than rot where PEX is concerned.

We’ll run the PEX up to the back of the house under a cover of soil and forest litter (there’s no digging through roots this heavy without power equipment) and split the cold water flow, capping one outflow for an eventual run to the instant propane water heater. The open end will divert cold water via smaller-gauge household PEX through existing wall cuts into the sink fixture (and eventually an outdoor shower fixture out back), leaving enough room for the eventual addition of the hot water tubing but secure from critters in the meantime. This will satisfy my main objective: adding running fresh water to the cabin. A little work aforethought will facilitate the later addition of hot water, and later a nice outdoor shower.

The previous tenants created an outdoor shower setup consisting of 6” PVC with the bottom end capped, then drilled and threaded for an on/off valve and shower head. It’s clunky, cumbersome, and ultimately unsatisfying to all purposes except fundamental cleanliness. The siting of the shower off of the back deck cluttered some of its usable surface and created perfect conditions for rot on the deck members below it. Neglect having been one of this cabin’s ‘problems’ on arrival, much of the work I’ve done since I moved in has been aimed at reversing as much of this neglect as possible. Hanging the future outdoor shower below the edge of the deck will allow me to keep the deck surface clear and mitigate potential causes of rot.f6f3e4b8c802f5eea37e0b409427d018-outside-showers-outdoor-showers

There’s nothing but bare soil around the cabin so the drainage for the outdoor shower will occur through the proverbial box of rocks: a likely collection of round, flat stones from the local beach and stream contained and isolated from the mud by a wood box, probably 2’x2’ in size: smaller than that pictured at right but not by much.

NOTES:

  • If you’re going to Craigslist to look for a used IBC tote (which I heartily recommend) make absolutely certain the container was used for food-grade contents only. These totes are also sometimes used to deliver chemicals, pesticides, and solvents that should permanently disqualify them for water storage purposes. They can’t be cleaned. Choose food-grade containers only.
  • Consider whether any/all of the materials you intend to use are intended for use with potable water. Are your fittings lead-free? Is the piping you intend to use susceptible to mold or rot?
  • Freezing is seldom a problem for us this close to the sea and sea level but depending on where you are you’d likely be well-advised to factor freeze resistance into your strategy to a greater extent than I have here.

General thoughts on pending restorations to the ‘Hobbit Hole’ cabin

Posted on

QUICK CABIN FACTS: I’ve calculated the enclosed square footage of this cabin as 273’ sq., including the loft and the ‘sun room.’ The construction is rough-hewn post-and-beam with kiln-dried members interspersed. Insulation unknown. Exterior cladding of shakes over marine plywood (of which I am suspicious). Interior floors of smooth-worn marine plywood just begging for me to find some nice, cheap oriental rugs. No indoor water except what you haul. All indoor lighting is either rechargeable or a combination of oil and candle lamps. There is no power at the cabin. Upon occupancy the cabin had not been thoroughly cleaned in years, and certainly never vacuumed since completion.

The improvements I’m set upon are in keeping with the limited scope and scale of this cabin and the ethos of the property as envisioned by the shepherd of this place, my landlord Alban.

  • I want hot and cold running water indoors and at an outdoor shower site formerly located below the cabin deck, on its south face.
  • I want to be able to flood the interior and proximate exterior spaces with light for living, entertaining, and winter sanity-preservation purposes.
  • I want to be able to charge a phone or laptop; maybe even power the odd low-wattage household appliance (e.g., immersion blender).
  • I want to build an two-part enclosure to process the cabin’s humanure (as recommended in Jon Jeavons’ The Humanure Handbook).
  • I intend to repaint the cabin’s outdoor toilet and rebuild its foundation.
  • I want to extend the beach-stone ‘walkway’ up and away from the cabin to provide downhill traction in wet months.
  • I am already collecting & cutting 1” sections of found wood to assemble into a corduroy footpath for some of the boggier spots on the 100m+ walk up to the cabin.
  • If I can locate an inexpensive source of sheet plexiglas or similar clear substance I want to build a small passive solar feature into a south-facing windowsill in the ‘sun room’ to help preserve the exposed window frame and shelter a section of the south wall of that room that shows a certain amount of past infiltration of water.
  • I intend to finish a cut and discarded piece of logwood by installing slabwood shelves, finishing with spar varnish, and securely mounting it to the corner of the deck.

Some of these projects appear pretty low on the list, as things that would be nice if I can get to them before winter. This cabin being the builder’s first, there are some fundamental mistakes that require thoughtful remediation if this is to remain a healthy place to live. Most important is to have spotted the problems. The ability to combine solutions for these with certain of the new projects listed above reflects my thorough, reflective nature and personal mania for efficiency.

The first project –the one I’m in the midst of now– is bringing water to the cabin, deeper analysis of which I will leave for my next post.

If you’re not going to proofread your own work don’t you think it’s a good idea to have someone else do it for you? What possible return can a business hope for from such a slipshod investment of time & resources?
