Most plumbers wont mess with the septic tank. We deal mostly with components inside the house. Did you have a vent pipe in the yard (often looks like a candy cane made of PVC) before the repair but not after? If all he did was replace the line it shouldn't cause a smell inside the house. All plumbing fixtures inside the house should have properly functioning traps. Those traps would create and maintain a water seal against the sewer gases. You should have at least one vent through the roof to equalize pressures within the drainage system. This prevents positive pressures within the system (caused by fixtures discharging into the lines, ie toilet flush) from pushing gas out through the traps, and negative pressures (the waste in line will pull air behind it like your finger over the end of a straw) from sucking water out of the traps.
CON'T FROM COMMENTS EARLIER. However, the installation took less than 3/4/ hour and was a basic regulator with no other function. Looking up the price afterwards, invoice did not list type or price, it appears that it would have cost me around $60 for the regulator and another $15 or so for the additional supplies necessary to install it and it was really a rather simple job with easy access. Given that, it seems that $300 for less that an hours worth of on site work, company says it does not include commute time in its prices, is a little high. While flat rate quotes are nice, they must take into consideration situations where the work load differs depending on the circumstances. Therefore, unless you are at the upper end of the harder work needed than the average job. it can be argued that my estimated price of $300 for labor was more than a little high. Maybe I am wrong since I have not used their services for years and am not knowledgeable of the costs of equipment and professional labor today.
Although needing emergency service for anything is never fun, if its plumbing service you ned I’d recommend Ben Franklin. The customer service person that took my call was courteous and professional. The service technician arrived well within the appointment time window. He was also courteous and professional. He understood my issue and explained what service was needed and what it would cost. He fixed the problem, cleaned up any debris that occurred during his work. We did the paperwork, he asked if I had any questions and then gave me his contact information in case I needed to call. You can’t beat that! Thanks!

Having the right tools can mean the difference between a quick project and a complete mess. Fortunately, you won't need too much to handle the projects here and what you will need is pretty inexpensive (certainly less expensive than hiring a plumber). You can get everything on this list for about $100, and you won't need it all unless you're doing all the projects. Where I live, that's about the cost of hiring a plumber for an hour.
Plumbers in Australia have licensing requirements that differ from state to state but it is generally accepted a 4-year apprenticeship with a further minimum experience of 2 years (6 years total) and a further curricular requirement as a benchmark for licensing. Licensed plumbers are also expected to maintain minimum relevant training requirements to maintain their plumbing license
