this will work right?? just ordered all the bits but with a 20mm pipe instead of 25mm.... im planning on running the inlet from a tank in my loft siphoning with a tap to control the flow, also made the pipe inside now 11mm outside diameter. will be closing of the bottom of the internal pipe and drilling holes to feed it just below water level.
should be fine right? a friend says he has a level stop tap i could use on the inlet aswell to stop the level raising to high if the outlet blocks up.
would i need to periodically add tap safe or would i be ok? planning on changing out 25 gallon per day?
