When that thing goes, 3 things. 1 get the gas pipe off the ground so that the moisture in the concrete and in basements in general don’t rot the pipe. 2 same deal for the tees on the left side that they used as leg supports for those risers, just use a proper hanger and get the steel off the ground. 3 replace the single pump with a bunch of zone valves. Always use multiple pumps and check valves. That way if a pump fails you don’t lose the whole house. A little more in up front cost but it’ll save you a serious headache in the future.
