Unfortunately, the boiler started leaking. Before winter, I flushed my secondary hot water heat exchanger and decided to buy a second one to replace it in case of contamination or breakdown. I was offered a more powerful used one. When it arrived, the lower pipe was bent, and I couldn't install it. They replaced it with a new one. I don't know how I installed it back then, but unfortunately, it started leaking from that lower pipe. Today, I couldn't install it until the retaining clip engaged, so I had to replace the old one. After I installed everything, water leaked from the pump valve when I started it. GPT chat advised me to tap on it to activate the valve and stop the water flow)))))). Thank goodness this happened when I was home and there was no frost. The large heat exchanger worked, but unfortunately, not for long. It was probably misaligned.
