Just dug up top of septic tank,once to lids,there is water there,water draining very very slowly out to field bed,could it just be baffle blockage,do I need new bed,can I keep tank and just replace bed?
In December we had to have pumped it was very full,and backed up a bit into bathroom tub,when we opened to have pumped there was some not a lot of solid in grey water tank,do you think maybe that the solids have blocked something somewhere along the line?Thanks Candace

Sounds like you drainage field is no longer working. Depending on your state's requirements, you may have install a new Aerobic system. In Texas, in accordance with federal law 92-500, you can not rework an existing septic system once it starts giving problems, you must install a new aerobic system. Check your state's requirements pertaining to 92-500 before you do any work on the septic system.

Not sure what laws are here in ontario.husband seems to think that maybe the field bed needs to be replaced,and could possibly use tanks as far as he knows.system not very old at all,think we did something by not pumping soon enuf.going to have pumped this week and inspected.will et you know.quite concerned with cost rite now.what is an aerobic system? Thanks Candace

Candace, an aerobic system consists of three tanks that initially collect all waste water, then pumps air through it which helps in breaking down the solid waste, after that chorine is mixed into the solution, and then it's pumped into the yard through several sprinkler heads.
Which Ontario are you located in, Calif or Canada?

Typical aerobic system here in Texas is about $6,000 installed
