Install sludge hammer 12 service plan (Install 05/19/2023) Installed sledge hammer unit. To begin this process I opened the septic tank up and removed the concrete lid that was still in place below the riser. Afterwards I dug a trench that the air line would be buried in. After the trench was dug I drilled a hole into the riser to allow the air line to penetrate the riser, then made a penetration on the foundation to allow the unit to be in the crawl space as per Patricia’s request. After both penetrations where made and pipe stubbed out they were caulked to ensure no seepage through the penetrations. After everything was plumbed in it was Tested to verify proper function and no leaks. Next I Buried the feed line upon completion of testing. Cleaned up job site after completion of work. Closed crawl space door back to how it was initially upon arrival
