    Question Question to a plumber from a sparky (with diagrams)

    OK, I have a client who has 30 plus greenhouses (which are pretty old) and I'm trying to find a solution to increasing humidity levels. There are already exhaust fans fitted up high at one end, and the air inlet comes up underneath, and thru a grill in the slab. Seeing as theres not much of a budget (love the recent economy ) the solution that I can almost see is as in the picture. Swampy pads in a box built over the intake, with a 100/200 litre tub and a pump dripping water thru the pads (well it's almost a swampy). To minimise wastage I was thinking of a gutter/tray to catch the runoff, and my problem is this..

    Can it be done with only one pump? I want the runoff to feed back into the reservoir drum, but I can't raise the box to a level it'll just drain in. The pumps we were thinking of using are your submergeable/pond pump type.

    Being a sparky (in australia) , I might be missing something every plumber knows, but if you don't ask, you'll never know!
    Cheers

    What about a recirculation pump with a water float switch in base to add in loss water ?

    I grew up on a farm. Lots of different types of greenhouses for different purposes. All of my neighbors had other types of set ups.

    I guarantee that whatever you're trying to accomplish, it's already been figured out and is being done commercially. The equipment is probably available off the shelf with no on-site engineering required.

    What is the goal? What are they growing? What humidity, temperature, etc. are you looking for?

    They're mainly for a certain type of orchid (Phy_ _ ?) I never knew, but apparently they're hard to grow well.

    Rather than a system, I was mainly wondering if there was some basic rule of plumbing that could come into play.. I figured the pump would suck air in with something as simple as a tee-off (one branch in main tank, other branch in 'drip/runoff tray').

    More of a 'clever trick' I spose you'd say
