How often do you clean out your septic? Since guests would abuse and do not use with care as family would .
I have a 1500 gallon septic and my home hosts between 2 and 8 guests. Even though I have signs requesting no food, feminine products, wipes, etc, down drain doesn't mean it is followed.
@Christie178 we just had to do ours, but I can't tell you the size, and we have 2 here. I think we are getting them emptied every 9 months, which is a bit more than usual but we have more humans here all the time now. I too have a sign on all the loos, but i rarely have any of my baggies used for fem products, so not sure what's happening. We had one blockage earlier this year - baby wipes. many many many baby wipes. We unclogged it ourselves but it was still an issue and luckily the septic guy cleared it on his visit.
@Christie178 We have our septic systems pumped once a year. We also have a plumber come and snake/clear the pipes from the house to the septic system once a year.
We had a massive backup one year due to an older couple who were sending adult diapers down the toilet. Like @Gillian166 mentioned, we also see very little evidence that our guests are following our suggestions about what can and can't go into our septic systems, and we are especially worried about baby (bum) wipe usage. Being proactive eases our minds.
