I purchased the Septic Genie and it has been working beautifully. It took 2 weeks for it to work and it has saved me a fortune. My field is like new again!!! I would like to know if you sell risers and lids?? According to your “photo” section, it looks very easy to install as my current lids are concrete and level to the ground allowing infiltration to occur. My Inside Diameter(ID) is 24″ of my barrel. What measurement do you need if you sell the riser and lid??? Thanks and look forward to your reply.
