Thanks for that...If you run them dry i.e they run out of water then they will die pretty quickly...where it says it will churn the same amount of water in the casing does this mean it will continuously push against the valve with an imense build of pressure? Or does the pressure divert back...

Thanks for the reply.. I am not looking to put more switches/sensors etc on the system as it is already built. I am wondering what happens if you block the output pipe on a bilge pump i.e does the pressure kind of back feed into the tank rather than continuously push and build up against the...

The system already has float switches for turning the pump on and off. The float valve is being used as a water inlet and for mechanical protection as the float is above the float switch that controls the pump. So in effect the float valve would only close when there is a problem i.e the...

Acording to what the guy who sold me the valve has just told me on the phone the float valve is rated Pressure - 0.05 - 1.0 Mpa (as of the Ebay description) From what hes told me this is the equivalent of 0.5 bar - 10 bar A normal UK tap is 1 - 4 bar acording to a plumber I have just phoned

hi all, I have one of these... http://www.ebay.co.uk/itm/Adjustable-Plastic-Float-Valve-3-4-inch-/270654338264?pt=UK_BOI_FarmingEquipment_RL&hash=item3f044174d8 And I wish to use a bilge pump to push the water through it... http://www.sipuk.co.uk/tools/info_SIP06819.html I am...

Its a 70 gallon polytank for a hydroponics system I am building...I am trying to get the very max amount of water inside it

Has anyone used these? http://www.ebay.co.uk/itm/Adjustable-Plastic-Float-Valve-3-4-inch-/270654338264?pt=UK_BOI_FarmingEquipment_RL&hash=item3f044174d8 The ball diameter is only 50mm due to its shape...a conventional ball valve is 4 inches (100mm) I am concerned about what kind of...

Hi all.... http://www.ebay.co.uk/itm/Adjustable-Plastic-Float-Valve-3-4-inch-/270654338264?pt=UK_BOI_FarmingEquipment_RL&hash=item3f044174d8 Any idea what flow restriction the above float valve might have against the traditional brass float valve of which has a low flow insert in...

So its another unattended ganga farm then! That will explain why you hide your location. As I have mentioned before one of my friends from school has owned a hydroponics shop for 16 years he gave me the idea for the phone controlled system of which is perfectly legal to design, build and...

It cant dump the water more often as it is using the mix within the main reservoir to feed the plants (hydroponics not soil) i.e the more they feed the more the main reservoir level will drop so the more I can get in here then the longer there will be before needing to top up the main reservoir...

This is not a conventional plumbing system that I am building. The tank in question empties completely via text message command then refills again on text message command using solenoid valves and pumps. The float valves on the system are for mechanical back up against electronic failure I am...

Thanks Tony...the system is already built so cant fit another tank or another valve...im looking for a low profile ball valve as of the original post

Hi all, I have a 70 gallon polytank (320 Litres) http://www.allplumbingsupplies.co.uk/Cold-Water-Loft-Tanks/25-Gallon-100-Gallon-Coffin-Cold-Water-Loft-Tanks/Polytank-PT2000-Coffin-70-Gallon-318-Ltrs-cold-water-loft-tank/prod_836.html?review=write As I understand it the 320 Litre line...

been looking for hours now found these http://www.plumbingsuppliesandfittings.co.uk/12_BSP_TF_x_15_mm_Capillary_wall_connector--product--132.html but cant find and 3/4" BSP ones. I would also prefer plastic Looks like I might have to try these...

building a perfectly legal system...650 hydroponics shops in the UK now

Or a 1/2" stainless A4 thin nut and a 3/4" stainless A4 thin nut fixes to some kind of L bracket of which will be bolted through the tank

I think the easiest way as far as fixing would be to get some kind of piece of plastic in an L shape and somehow cut a 1/2" bsp thread into it and a 3/4" bsp thread into it and bolt the other side of the L through the tank..sealing with washers etc

Its for a mobile phone controlled hydroponic system ive been working on for several months...electronics side is no problem its the plumbing, fittings etc that are driving me mad

Hi all, I am pulling my hair out here.. I am trying to fit one of these http://www.omega.co.uk/ppt/pptsc.asp?ref=CDTX300 (the probe of which is 1/2" bsp thread at the end of the probe and 3/4" BSP thread and the cable side of the probe) and one of these...

anyone any further ideas on this please?
