Hi! On this occasion I have to connect a new hot water tank since the one that was punctured. I already bought it and everything but I have a doubt. The hot and cold water connections on the wall are higher than the thermos. About 10, 15 CM more. From the wall there are two flexible ones that connect to the thermoset. The easiest thing for me is to take out and put on the new one but in the manuals I see that in the hot water outlet they siphon it but in all the schemes the hot water goes down. I have the hot outlet above the thermos. Is that siphon necessary in my case? If so, how do I siphon up? Now I paste a picture of what I mean.

hello: the siphon is already done by the pipe itself inside the wall connects as was the previous one with flexible and ready it is well greetings
