I was wondering if anyone has plumbed up a de-liming set-up into their DHW coil? What fittings did you use?
Thanks!

A pair of tees and a pair of boiler drains.
A pair of isolation valves to stop the flush from going downstream.

Thanks! I am thinking of a small pump with some clear type hose to do the de-liming.

After thought, best to remove one of the handles from isolation valve after deliming
If for some reason both were closed there is no room for expansion and pressure would climb some in the coil.

2 hoses a pump and a bucket

water-heater-flushing-kit

Tankless-Water-Heater-Cleaning-Kit

you can see what's going on in the bucket and you may strengthen the recipe or even toss the spent chems and start again with another batch of new full strength chems.

Good Pooint. Also, there should be a 150 psi relief valve on the coil piping.

150# seems kind of high.
