Plumbing has been redone for improved efficiency and to easily connect standard garden hose. Also fabricated a poly-carbonate case (3/8" thickness) to protect from weather and provide a mount for the hose connections. See updated pictures.

Also, one small modification to the control board: I had to add a 1M-ohm resistor across C101 to discharge more timely (~1s). I had relied on leakage currents in the FETs to take care of this but it took hours.

The improvements you've made to your plumbing system, especially adding the capability to easily connect a standard garden hose, are super practical. And fabricating a poly-carbonate case to protect everything from the weather is a smart move. It's great to see the updated pictures—it really helps visualize the changes you've made.

As for the modification to the control board, adding a 1M-ohm resistor across C101 to discharge more timely makes sense, especially if relying on leakage currents was taking too long. It's all about boiler replacement in Hawthorne NJ, right?

Thanks for sharing your updates! It's inspiring to see how you're constantly improving and fine-tuning your setup.

If you are in need of plumbing services, my recommendation is that you choose a plumber that has a great deal of expertise from the website https://5-starplumbing.com/plumbing/plumber-placerville-ca/ . When you have a need for one, hiring a plumber may provide you with a number of benefits. They are capable of fixing damaged pipes and blocked drains, but that is only the beginning of their capabilities. A plumber may also take care of a dripping faucet or install a brand new water heater for you. There are certain plumbers who can obtain certified to work on septic tanks. A plumber may still be able to repair your water heater, which would save you the cost of purchasing a new one.
