you dont know anything about the project..ive been working on it for 4 months at a cost of around £2K It has 15 input commands and 16 output commands, 2 x cameras, water sensor alarm, smoke alarm, motors, dosing pumps etc etc The UK, US and Canadian hydroponic forums certainly dont consider...

If this is all operated by phone command from a distance, how will you know if it's flooding? :shock: :shock: :shock: Do you have a float switch in the reservoir to shut the solenoid? the main reservoir tank has its own ball valve of which is its mechanical protection. Once the command is...

Now im wondering how im going to get fixings onto the round water butt.. i.e if I go and push a 3/4" ball valve into the top of it I wont be able to get it to seal unless it has curved washers or something If I cut the existing drain tap out of the bottom of the butt I will then have to...

Thanks for your replies... The solenoid valve on the main tank is 3/4" with a reduction due to a hose tail on it going to a 1/2" hose pipe..so to increase the flow I am asuming I would need to buy a bigger solenoid of which are expensive... If the main tank is 100L and the water butt is...

Hi all, I have been designing and building a hydroponics system thats controlled by mobile phone for the last few months in my spare time. A friend who I have known since school has owned a hydroponics business for the last 10 + years and he asked me to design a system knowing I am into...

works a treat :) £18.00 + VAT (UK)

Just had a read of this old thread and am having the same problem.. The answer as I see it is one of these.. http://www.interfacesolutions.uk.com/ You need to IS-ARM on the products page

I am going to get this one tomorrow.. http://www.toolstation.com/shop/Plumbing/Pushfit/Double%20Check%20Valve/d20/sd3143/p83191 This is a double check valve..im having problems understanding what that means..can I simply push the copper pipe into each end, drop it in the main tank and it...

What about this one... http://www.diy.com/diy/jsp/bq/nav.jsp?action=detail&fh_secondid=10457551&fh_location=//catalog01/en_GB/categories%3C{9372015}/categories%3C{9372046}/categories%3C{9472012}/specificationsProductType=valves/specificationsSpecificProductType=double_check_valves or this...

Holy cats alive...the fu##ers still dribbling when the pump turns off with valve in main tank with compressions and jubilees

This sounds like a good plan...the valve came with 2 x compression glands with olives the problem is I have heard hydroponic nutrients dont like copper pipe. im going to give it a go now, drop the valve, glands, copper tails and jubillees into the main tank and see if the dribbling stops I will...

Its a hydropnics project...see a few posts back

Thanks Chris...that look like a good plan..trouble is I havent got the room in the main tank due to 2 other pumps, switches, cables etc to come up then back down..

What about this one... http://www.seascrew.com/browse.cfm?PLASTIC-ONE-WAY-VALVES---STRAINERS&l=0000000408 The 1/2" or 3/4" one down the page? It all depends on what pressure opens the valve though and if it can be submerged in the main tank..

The problem is I dont have the fittings nor know where to get them and I dont want to fit the brass valve inside the main tank as it will be submersed 24/7 hence why a plastic valve would be very good with hose tails on the ends..ive been all over google but not much luck..hoselock do one but im...

Anyone any ideas?

There is still a slight dribble coming through the valve :twisted:

Ok...this is the answer. Ive just fitted one to the smaller tank on the actual tank side where the water pours in. I got a standard brass one but the water pressure of the pump dosent push enough to open it properly so when the main tank is half full not a lot gets through but when the main tank...

Thanks for all your replies.. I have now changed the main tanks pump outlet position so it is right at the bottom of the tank.. I have just tested it and its still filling up the smaller tank when the pump turns off The pipe is flat against the floor apart from where it goes up and...

its for a project im doing where I am not sure where the end user would position the tanks so I would rather use electronics.. So where you say an air inlet if I got a small piece of 1/4 plastic, pushed the 1/4 hose on both ends in the top of the main tank then drilled a couple of holes into...
