Thread: Pressure pipe

  1. #1

    Pressure pipe

    I am sure this one has been done to death. I am currently looking at buying a spindrifter bottom drain. 4Ē. Kockney koi do an all in 3m kit with pressure pipe. However i am wondering if I can get away with ordinary waste pipe? Iíve read that the pressures involved with ponds are very low and pressure pipe is overkill. Does anyone have any thoughts on this?

    Have a go at the search bar for some of the threads on this mate. But personally I have used 110mm waste pipe in my build as has @Ukzero

    Used both, 110mm and 4" class C.
    Depends on how you are building.
    If a concrete block build 100% pressure pipe
    If not either is OK.
    But not much difference on price especially once you start adding 4" ball valves....

    Everyone keeps mentioning these. Is this some new kind of mysterious device? Sounds like witchcraft to me.**


    **Please note that this post intended as a tongue in cheek quip. I do know what ball valves are. I just have a habit of doing things differently.
    I'll only put this in tiny writing as it's a contrary view, but after consulting a couple of pipe manufacturers some years ago they advised ring seal pipe underground if there was any chance of settlelement or movement. The theory being that ring seal fittings tolerate movement, but solvent welded fittings don't. For exposed pipe work I would say either is OK, but ring seal pipe runs would need something to prevent the joints sliding out (brackets/cable ties/etc).

    Lol
    Your own invention for valved control was truly inspired.
    And very well executed.

    I like simplicity of design too, but have a penchant for complicated pipework as an ex pipefitter lol...

    Probably why my mainswater purification is so complicated...
    That, and crap mains water....

    Actually your comment should have read "inspired...by penny pinching".

    Don't get me wrong - there's something deeply satisfying about showing off well executed complicated pipework to fellow enthusiasts.
    I do have a 50mm 3-way stainless steel ball valve sat in my garage gathering dust. It had been acquired for making up a DIY motorised valve but I went back to my simple ways.
    I think the valve is rated at a gazillion psi and so would have really impressed down the pub!

    you could hook up the motorised 3 way valve to the waterfall feed, and control it to divert the flow via a thermostat,
    so when the temperature was too cold it would return straight to the pond.

    automation can go too far though lol
    i still miss cleaning my black knight filter brushes...in summer...you can keep them the rest of the year...

    Funny you should say that. I was actually thinking of using the valve for the waterfall with filter V1.0 but glad I didn't because now I use an air lift, well, air lifts are good, but not that good!
    Because I have an outlet chamber in the filter shed from where I can add extra air or divert back round the filter or add bicarb or treatments I just dropped a submersible pump in there for the waterfall. Nice clean water, no effect on filter water levels and easy access for maintenance. We only operate the waterfall when we're in the garden. System doesn't need it and remember my penny pinching habit

    Tap water treatment is the part of my system which I know I might not be paying enough attention to, so reading stuff on here with interest.

    tap water is so regional it's ridiculous...

    some places have 0 KH, 1ppm nitrate, and next to no chlorine, you can nearly add it straight to the pond...

    other places it comes out of the tap in lumps and you have to break it up with a hammer....

    If you have a high water table it might be worth digging a well?!

    Not here,
    my house is built on a brownfield site.
    An old brickworks and colliery...
    Most plants die if planted in the grey 'clod' they call the soil...
    A mix of brick bats, slag heaps, coal noggins, and reinforced concrete...

    Interesting talk and very informative so let's get back to Clives question.

    Really Clive it's up to you mate as if myself or someone else says yes go for the waste pipe and it goes tits up for you then we would feel responsible.

    My pond has waste pipe but glued under ground ( you can glue push fit pipe ) but above ground I have mostly 110mm waste push fit to my drum with no problems at all.
    A lot easier to fit and adjust as opposed to glue figments.

    So really up to you,soil pipe is strong and you can use the brown underground as long as it's not exposed to UV sun.

    One word of caution about solvent welding waste/soil pipe. The solvent fittings are obviously going to be OK but the pipes need to be suitable for solvent welding. Some of the underground (brown) pipes in particular are not suitable. It doesn't help that the OD are identical in many cases. Always try a bit of solvent on a scrap piece first - if it doesn't eat into it quite quickly then don't try and glue it. Always try and get PVC pipe (black soil pipes are usually PVC based).
