know it sez diy but you determine mtl selection,,, we 'butter' crks w/hydraulic then drill for injection ports,,, sometimes we remove 'butter' but only for aesthetics.
you meant low pressure, right ? anyways, sometimes ports come right out OR they're a large pita,,, any success depends on installer skill & mtl selected,,, i never used surface ports - they're for diy'er wannabee's impo,,, when i learned as the 'helper' it was 5yrs before any installing company let me put my hands on their guarantee.
suggest either do it right OR call a pro - here in atl the rate's about $ 750 for a wall crk including mtl,,, the nice part about it is you don't have to wonder who to call back since you didn't diy :no:
ps - have used appliedtechnologies & had no issues w/their mtl
