  1. This is practically identical to my setup... You basically split the waste (red) output line into two paths... one with a ball valve and the other with the flow restrictor (may have to acquire a new one if your unit has the tiny type hidden in the outlet elbow). The pipes then rejoin and run to waste. When the valve is closed, water passes through the flow restrictor as normal and pressure is increased on the membrane allowing for normal operation. When the valve is opened, the water (under pressure) will rapidly follow the path of least resistance, which is now the unrestricted side and the fast flow will help flush particles off the membrane as it passes by. Do pay careful attention to the direction on the flow restrictor... they only work in one direction and must be installed that way. I'm not sure if it is beneficial to keep a bit of pressure in the system. I personally tend to shut the outlet pipes first then finally the input just to make sure it is definitely wet when shutting off and limiting the chance of air in the system.
  2. Is that the one you linked to previously? If so, make sure you take note of the warning; "should not be used for periods longer than 60 minutes at a time, a 120 minute cooldown period between uses must be allowed" If you run it extensively without following that advice it'll burn out quickly. A simple timer socket will allow you to set intervals if necessary.
  3. Zerbirus; you're welcome. Sounds like you're all sorted and as you have near optimal pressure around 60psi, I'm not surprised you're getting efficient ratios of clean:waste water. osmosis; yes that's correct. The flush kits have a flow restrictor in them so you need to remove the miniature one concealed in the outlet elbow. A pressure gauge is good for monitoring, yes. I have mine installed just after the pre-filters, before it enters the RO membrane. That way i can tell if the pre-filters are clogging. Don't forget to hook it up first at the very start of the system to get a baseline value for the mains pressure (i.e. what it should be).
  4. If you need help identifying the bits, post a pic and I and/or others will have a look.
  5. Thanks Rich. Yeah the one front right is deliberately lower (even though it spoils the very neat unified look) to accommodate my taller flava collection, otherwise they'd not only be squashing against the roof but it becomes hard to see and get to those furthest back! Also have a 60cm-ish area immediately front right (can't really see in the pics) that has no staging allowing for real monsters and/or huge multi-crown potfulls in future.
  6. Hi Phil, It happens to be one of my favourites... an S. oreophila 'De Kalb' x S. flava var. rubricorpora [MK-O5 x MK-F45] Grows tall, with a wide throat, big lid, great venation then suddenly turns completely maroon red (as it has done fairly recently).
  7. Hi all, I installed the last sections of staging (all home made) in the greenhouse over the weekend and all is looking much tidier now! Very pleased with the look...

    Thinking About Picking Up a Ceph

    It looks like a flower stalk shape but looks browned off in that pic, as though it has been aborted. As Argo says, a closer pic would help. As for water, I'd fill it right up and not worry too much about it having to all disappear before topping up. That's a high enough pot and they like water much more than they like dryness.
  9. Yes a pressure gauge is a very handy addition. I added one on mine as it allows me to quickly check at a glance that the mains pressure is where it should be and will indicate if a leak ever occurs.
  10. Yes you can get a rebate if you can prove that none of your surface water drainage (i.e rain guttering enters the sewer). I don't think simply saying you use water butts would cut it though, even if you had one on every downpipe, as the way the diverters work is by letting a fraction of the rain into the butt so you're still having some go down. With this current heatwave and water shortages looming, with some districts already being asked to "kindly restrict use of non essential sprinklers and hoses", if I did try for a rebate, they'd probably come back telling me to stop using so much water... just for plants!
  11. The one Chris has and posted is very good value and comes with everything you need. I doubt you'll find ones much cheaper than that, and if you do I'd be dubious of their quality.

    ASDA plant

    Nice looking purp and with tender care, it'll only get better. I've seen those pots in my Asda as well, nothing much to interest me yet but good to see CPs still turning up in mainstream shops.
  13. Actually yes that is correct! I just looked into it and sewerage is charged at % of water used (as read from the meter)... 92.5% for my Water supplier. You can apply for a rebate if you can prove you are not using that much, i.e. in my case of drawing a lot for RO but not using the sewer to return it. Might look into that and what evidence they would need. Otherwise, I may as well just run the waste down the drain. Deltango; definitely fix that leak as RO systems need to work under pressure and a pressure loss will affect your output production volume. Chimaera; any RO unit can be attached easily to a hosepipe via a standard 3/4" female bsp to 1/4" push fit quick connector, which are very often supplied with RO units (as is the case with the one Chris recommended.)
  14. Forgot to say; if not already obvious, those on a water meter want to avoid letting the waste output run down the drain. There will be a large amount of waste water (4x good output or more) and as sewerage rates are higher anyway, this is where costs can soar. Just run the pipe onto a garden and/or a soakaway instead, then you only pay the rate of drawn water from the mains.
  15. I'm guessing the people that report clogs and poor performance are those that do not follow advice such as what I posted about proper (wet) storage, periodic flushing and good practice. As an example, I stopped using mine late autumn last year, finally disconnected and stored indoors over winter, and re-commissioned into use around April/May this year. Therefore, it had been unused for about 5-6 months and I hadn't bothered flushing during that time (my bad!). When I first hooked it up, I tested the output and it was at 80ppm. Oh dear, I thought I may have to get new filters as it didnt change after flushes for a few minutes. However, as a last effort I left it flushing for about an hour and low and behold I was back down to under 10ppm. This is the importance of a flush kit and why I advise everyone installs one. Without it, I would probably never have resurrected the RO membrane and had to replace.
