    SB, you may have covered this in an earlier post, I was wondering what is the optimum angle for your solar panels (photovoltaic), down your way? Up here in the NE Victoria it's near enough to 40 deg.
    Yes, I'm still toying with the idea/dream of moving down to Van Diemans Land and was considering a shack similar to the Eco Hut on the Kimo Estate near Gundagai.
    Needless to say that angle would dictate the angle of the roof.

    Hi you all, I have been working so hard I have had no time to update this thread let alone look it up so a big sorry for taking my eye off the ball.

    So how is it all going? Well I'm still building but now at the finishing stage, hope by August this year as the Building Surveyor has said no more building permit extension under the old BCA as the new BCA will be active and I may have additional compliance to meet so it's full pace now to get it all done and dusted. A couple of decks to build, some floating floors and outside sealing to meet the BAL 29 and then some landscaping. Cal, you are welcome to drop in when you are in Tasmania if you want. I just finished laying the floor tiles in the kitchen, laundry, toilet, storeroom and back entrance, what a job on your knees all day. Got all bedrooms and bathrooms finished along with electrics finished. Now two and half years with the off grid power system working like clockwork. The thermosyphon hot water system works a treat with the wood burner in winter and evacuated tubes on the roof in summer.

    Now for some pictures. Sorry they may not all be the right way around.

    another finished room,
    kitchen and newly laid tiles,

    Fantastic work! Sorry, I have been a little busy lately myself this is the first time I have seen your reply. If I get the opportunity while we are in Tasmania, I would love to come and have a sticky beak at your handy work. The house looks brilliant!

    Boy have I been busy, now got the upstairs deck finished in spotted gum and the Peak balustrade system installed. The balustrade has to meet the BAL29 rating, I also ran it past my building surveyor as he told me not all balustrades from the big green shed are or were compliant. Enjoy

    Hi guys, I am experiencing a house water pump issue. I have an outside water pump (orange brand) that supplies water to my house from an above ground water tank that is full right now and has been for a few weeks. The pump supplies directly to the house when a tap is turned on. The pump is about 3 years old and had been working very well. We used to get good water pressure as soon as you turn on the tap ie no delay in water pressure. In recent weeks, however, when we turn on a tap the pressure is low for about 3 to 4 seconds and then comes up to the full pressure we used to get instantly before. I have checked the plumbing system and no leaks and no blockages or filter problems.
    So from people’s experiences with their house supply water pump, is this a sign of a failing pump that needs a service/replacement? I suspect it is the water pressure sensor on the pump that has had its day but I'm not a water pump expert nor have experience in diagnosing pump problems.

    Show a pic of the pump pressure regulator and I may be able to suggest a fix.

    There will be a rubber air bladder that operates the pressure relay switch that turns the pump on and off, These usually have a spring in the bladder housing that has an adjustment screw to adjust the cut in / cut out pressure. The bladder will probably just need an adjustment as the rubber bladder does leach out air over a period of time.

    Well that's an interesting one. It is the SJ400-PM model, I’ve included a couple of pictures, rebuild, is the bladder in the stainless steel part? I'm a fairly practical hands on guy that is usually able to fix anything if I know something about it.

    Bohdan, as you can see I hope by the pictures what you need.

    Nothing to do with your current woes, but I did come across a fascinating old tech called a "ram pump".

    These things, using nothing but a flowing water supply, can pump water up considerable hills.

    Perhaps useful for a gravity fed system?

    Bladder is in the unit on top of the pump where the power leads are attached. The spring will be in the barrel piece from the made body of the control unit. Also check the points on the pressure actuator where they contact on the circuitry. From memory the pump should cut in at 4 bar and cut out at 4.5bar. I assume you have a removable cover for the pump, if not then you need to.

    Have you tried just bleeding the pump yet

    If you undo this bolt just a few turns(It’s a bleed valve)
    You should get a steady stream of water(Pi..)
    Come through,When it’s running strong the stream lock it off,there will be another one possibly lower down as well on the unit.
    You may just have an air pocket in the pump.



    Cheers Matt.

    When the tap is turned on the water pressure on the outlet side of the pump drops, the bladder or piston in the unit on top moves in and activates the pump. They are not usually adjustable as the switching is done by a series of magnets mounted in the shaft attached to the piston/bladder. If there is a delay in the pump activating it may be that the piston is not moving freely. This can be checked by removing the horn from the controller and checking for free motion.

    Make sure that the power is off when you remove the screws, a small quantity of water will squirt out unless you open a tap to release the pressure.

    If the piston is free to move then there may be a partial blockage preventing water from releasing pressure on the bladder rapidly.

    Ultimately the best diagnosis is to fit a pressure guage to the pump outlet and if the pressure drops and the pump doesn't start immediatly then the controller is faulty and should be replaced. These controllers are expensive if bought locally as a spare part but they are very cheap direct from China.

    Most likely you have some partial blockage in the system and the real trick is to find it.

    Do you have an input filter on the pump? This will keep a lot of rubbish out of the works and stop these sort of problems. I have had a bird skeleton in mine before I fitted the filter and the beak damaged the pump impeller.

    Well guys I have some direction on this now, I just need the time to take a look and check things out as suggested by rwbuild and bohdan. I did find an internal diagram for the pump that did not show a bladder and now you have said it's in the top part of the pump with the electricals it stands to reason why I hid not find it on the diagram as they sell this pump without the top part also. I'm looking forward to finding the problem. Simplicity, the pump is self priming and the tank is slightly higher than the pump so no problems with priming or water flow.

    As I'm under the gun to get my house compliant by the building surveyor I'll just monitor it for now till I get some time. I was thinking of buying a backup pump anyhow and just rotate the two when they require maintenance so I always have a good pump on hand when need.

    Thanks guys for your help and giving me some direction on this
