Hi All,
I'm looking for you plumbing experience advice on the task i'm trying to accomplish.
Apologies for posting this question in the general thread since did not find a better place to post.
I'm trying to build a drip system that would be connected to both cold and hot water (tank) supply and would drip on the end. The system should:
1. allow controlling precisely (at least in steps of 1 gph) the flow rate down to full stop.
2. provide steady controllable water temperature (70F and up) at the outcome at the low flow rate (0.01 gpm)
3. be fault tolerant, meaning if the cold water supply stops the flow should stop, if hot water supply stops it should continue on the cold water.
4. long lifetime
5. use 1/2 inch pex for connectivity
I've done a bit of research and my thoughts are:
1. irrigation emitters can be used to precisely control the flow rate
2. low temperature T/P mixing valve can be used, but most manufacturers claim a steady operation with a flow over 0.5 gpm, which is much higher than 0.01 gpm. May be instead use pressure balanced mixing valve with the sort of temperature controller?
3. add additional "T" section to manually override the mixing valve?
4. ?
5. should not be hard to find various connectors.
thank you!
