Sounds to me like he's got the pressure up to high. What pressure should the system be set at? How can this be adjusted?
Is something wrong if the regulator is continuously bleeding off gas? or is that just because the pressure is set too high?
Go to a home brew store and get a bottle of star San (he's gonna need it anyway come time for cleaning and sanitizing (should have already sanitized, btw). Star San is good to put in a spray bottle then spray it around all the connections to see where the leak is. There's no reason the regulator should bleed gas unless the pressure exceeds the ability of the regulator, which is doubtful that's the case. The two tanks I lost (both same day) when I first started were leaks at connection points where the hoses attached to barbs. The beer being way too foamy is pretty generic and without more info there's no way of knowing. Is the beer blasting out of the faucet? That's the first sign of too high of pressure. You should have him reduce the pressure to 10-12psi and see what happens. If it's still coming out pretty forcefully and foaming like crazy, he needs to put on a longer beer line. My first faucet was a "kit" that came with a 5' line. According to all the calculators online 5' should have been right to balance my system, but it was still too strong of pressure coming off the faucet. The #1 rule is to set your pressure ACCORDING TO YOUR BEER. Set the PSI to what it needs to be to maintain the appropriate CO2 volume, then trim/add beer line as needed to slow down the flow and keep the beer from being too disturbed while coming through the line, shank, and faucet.
There are calculators you can use to "balance" your system, but as long as you set your PSI to the beer you can add 7 or 8 feet of beer line then trim and test until you find what you like.
