Drained the system partially to allow cleaner to be added via filling loop as recommended in instructions. The canister ran out of propellant after 8 secs (apparently the process only takes 20 seconds) leaving more than half of the fluid still in the cannister. Couldn’t get anything further out even when vented to atmosphere. I would stick with conventional product/container at half the price.
Absolutely useless, plastic threads wouldn't seal, most of product ended up in bucket. Had to drain system to add. Far cheaper to buy ordinary can for half the price.
