  • Water Shutoff Valves: Autopsy

    Water Shutoff Valves: Autopsy

    After a bit more than half a century, the rubber washer in the cold water shutoff valve for the kitchen sink had fossilized:

    Sink shutoff - cold washer
    Sink shutoff – cold washer

    The hot water washer was in much worse condition:

    Sink shutoff - hot washer
    Sink shutoff – hot washer

    The shutoff valve for the hose bib in the front of the house, mounted knob-downward, has been dripping quietly for many many years before I replaced it:

    Hose valve shutoff - knob corrosion
    Hose valve shutoff – knob corrosion

    I’d turned the valve off to no avail, so this was no surprise:

    Hose valve shutoff - washer
    Hose valve shutoff – washer

    While it is theoretically possible to replace those washers, even the professionals know better than to disturb a sleeping valve:

    The tandem valve was likely installed half a decade ago, along with the dishwasher it services. Perhaps the washer inside remains soft.

    As If Your Life Depended On It

    Spotted on a scissors lift outside a grocery store being remodeled:

    The SkyJack instruction manual explains the symbols, although some of the Quick Start instructions remain baffling.

    We had great fun making up captions to suit the pictures …

  • Bathroom Faucets: User Interface FAIL

    Bathroom Faucets: User Interface FAIL

    The sink faucet in our motel room worked the way you’d expect:

    Grohe sink faucet
    Grohe sink faucet

    It pivots left-right to adjust the temperature and lifts to control the flow, which is Off when the handle is parallel to the sink countertop.

    Evidently, everybody assumes that’s the way the identical faucet handle works in the shower, despite the helpful label:

    Grohe shower faucet
    Grohe shower faucet

    Did you notice the minuscule red dot below-and-left of the handle or the corresponding blue dot just to its right? Absent the label, those provide all the hints you’ll get as to how the handle operates.

    The faucet body & plumbing were loose in the wall, as though many previous people had given it a firm yank to get water out of it.

    I’m 3.5 diopters nearsighted and can’t see those little dots. Mary is 2 diopters farsighted and can’t see the label or the dots.

    What did they think would happen with different valves having identical affordance?

  • Home Depot Glacier Bay Kitchen Faucet: Round 2

    Home Depot Glacier Bay Kitchen Faucet: Round 2

    The kitchen faucet worked its way loose again. Attempting to shut off the water revealed a pair of leaky valves under the sink, so I shut off the house water in the basement, cut the valve pipes below the solder drips, and installed a pair of push-connect shutoffs:

    Kitchen faucet shutoff valve - push connection
    Kitchen faucet shutoff valve – push connection

    I loves me some good push-connect fitting action, which is new news to me. Back in the Bad Old Days™, I’d be under the sink with a propane torch, trying to solder a pair of wet pipes and failing miserably.

    With that out of the way and the faucet dismantled for the first time (by my hands, anyway), the threads holding the base to the spout column may have been damaged during factory assembly:

    HD Glacier Bay kitchen faucet - damaged threads
    HD Glacier Bay kitchen faucet – damaged threads

    I thought the gunk was thread lock compound, but it’s shredded plastic from the base fitting threads. The corresponding female threads inside the spout column are undamaged, so I think somebody tried screwing it together with the threads misaligned, backed off, then muscled it together.

    It’s worth noting there are no keys or stops fixing the correct orientation of any of these parts. In particular, the trim ring bearing the small Front label (facing you in the picture) has no fixed orientation: whoever assembles the faucet in the factory must position it correctly on the fly as the base screws into the column and jams tight.

    So I cleaned up the damaged threads as best I could, flipped the threaded brass tube end-for-end to put the cleanest part into the base, and reassembled everything with careful attention to starting the threads correctly:

    HD Glacier Bay kitchen faucet - flipped brass tube
    HD Glacier Bay kitchen faucet – flipped brass tube

    Tightening the base fitting into the column is much easier with everything on the kitchen counter, although centering the label on the molded opening required several tries.

    Protip: a pair of grippy gloves and rubber sheets help a lot.

    I want to find out how secure the original design, properly tightened and aligned, will be, so I did not apply any threadlocker.

  • Wheelbarrow Drain Holes

    Wheelbarrow Drain Holes

    Attacking a plastic wheelbarrow with a ¾ inch hole saw prevents it from becoming a mosquito breeding station:

    Wheelbarrow drain holes
    Wheelbarrow drain holes

    We had been storing it tipped to one side, resulting in the wheel filling up with water, which can’t be a Good Thing.

    If it must carry a load of sand, I’ll just duct-tape the holes.

    One of Mary’s friend looked at, but did not order, this wheelbarrow on Amazon. Shortly thereafter, she received a wheelbarrow in two packages: the handles and a box with everything else strapped into the barrow. After a discussion with Amazon’s support / help staff, she was told to just keep it at no charge.

    Over the next few weeks, she received five more wheelbarrows, each prompting a discussion and keeping them at no charge. Eventually, somebody figured out how to stop the stream.

    So half a dozen gardeners now have free wheelbarrows, courtesy of a glitch in The Machine.

    Makes you wonder, doesn’t it?

    Having an aversion to getting slapped in the face by Blackthorn branches overhanging the Dutchess Rail Trail, I generally give up waiting for anybody else to do the job:

    They’re not all Blackthorn (Prunus spinosa), but Ailanthus altissima grows like a weed around here and requires heavy cutback:

    Three months after we were told they had ordered replacement tiles, I’m beginning to think I must buy some on Amazon and do this job myself, too:

    At least they caught it before the end of the row.

    Verily, it is written that Computer Science has only two hard problems:

    • Cache invalidation
    • Naming things
    • Off-by-one errors

    I hate it when that happens on my projects …
