seb88 Posted September 7, 2020 Share Posted September 7, 2020 I'm trying to figure out how best to connect my blumat system to my nutrient resevoir but I'm a bit confused with all the different standards and fittings. The blumat system uses 8mm hosing and I need to connect this to my nutrient tank. The kit does come with a tank connector but it means drilling the tank and I'd like to avoid this if possible. My tank already has a 3/4" BSP threaded hole in the bottom corner that I want to use. There is a company in USA called 'sustainablevillage' and on their website they have a 'blumat filter - clear bowl 8mm'. It's a filter with the required 8mm hose connector for the blumat, and they have a few options to connect to 1/2" and 3/4" slip PVC. They also mention they can supply a 3/4" hose thread adaptor. Will any of these options work with my 3/4" BSP fitting? Or is BSP a British standard thread that none of these will work with? I have the option to buy a 3/4" BSP shut off valve with either a 3/4" or 1/2" hosetail that I can connect to my res, but unsure how to get the filter connected to this.... I'll grab some pics to try clear things up but I'm hoping somebody with a better idea of fittings/standards will have an idea of what I need!

seb88 Posted September 7, 2020 Author Share Posted September 7, 2020 Tank with 3/4" BSP threaded hole Tap kit / shut of valve - 3/4" BSP to either 3/4" or 1/2" hosetail Blumat filter - 8mm adaptor for blumat Options from website 'For the same price, we can also ship this with fittings for 1/2" drip, 3/8" drip, 1/2" & 3/4" slip PVC. For a little extra, we can provide a fitting for 3/4 hose thread or any combination of the above.' Can I just buy some 3/4" 'slip PVC' (whatever that is?) and use this to connect the filter to the tap kit above? Link to comment Share on other sites More sharing options...
ROCKSTEADY6 Posted September 7, 2020 Share Posted September 7, 2020 Hi Seb. I think i might be missing something but can't you just use one of these? Sorry the pic is so large. 8mm hose connector with 3/4 inch to connect to your tank. Surely then the filter just joins into your 8mm feed line after it leaves the res. The filter I use is one unity recommended and is much smaller and seems to work well. I think it was meant for car engines or petrol or something similar. 2 Link to comment Share on other sites More sharing options...
seb88 Posted September 7, 2020 Author Share Posted September 7, 2020 @ROCKSTEADY6 cheers mate I did see those on eBay and they mention an 8mm hose tail, but the photo is out of proportion, looks more like a 20mm but hopefully it's just a stock photo they use for all sizes. They are cheap enough so I'll get one ordered and see if that's right 1 Link to comment Share on other sites More sharing options...
