Yes, that wouldnormally be in the DIY range with a fewtools and a bit of grit!
It may not be fun as it is a "dirty" area if we think too far?
But that is the vlave and likely has a cable, etc on the backside, so a look at that before committing to the job?
But even before that look, some thought about where exactly the leak might be, can save a lot. Is it leaking around where the metal seal are holding it, so that tightening the seal might compress the rubber and stop the leak?
Or is it leaking between the plastic parts of the valve and tightening the bolts that hold it together might do the job?
