DIY tank refill system

After various threads and various different ways of refilling my tank I decided on a 3 way valve system on the external filter

I was previously taking the R/O water and pouring it into a bucket that was wide enough to put an old internal filter in and pump the water up to the tank.. but this was a clumsy way that was hassle and work

after looking at a system someone had designed I decided on a 3 way vale on the intake tube on the external filter

To prime the system i put the tube into the container I fill from my R/O barrel

turn the flow valve to left and it takes from tank still but floods the container with tank water... flushing out the air

then turn the flow valve to the middle which diverts water from the container instead of the tank

into the filter and then out the spray bar!

nice and slow fill up so less shock to the tank and I can sit back while the tank fills up


the part only cost me 7 on ebay and some cheap PVC tubing and a couple of clips to keep it all tight
