UNION GAP, Wash. - Valley Septic in Union Gap said to keep a close eye on your tanks.
If you hear anything out of the ordinary coming from your tank, be sure to contact a professional septic tank service to check it out.
Valley Septic's Scott Liniger said the problem doesn't really come from the cold months.
Instead, it's the hard ground that septic tank workers have to dig up to get to the tanks, which poses a challenge.
Liniger said regular maintenance of your septic tank should keep it flowing well.
He recommends that you have it pumped every three to five years.
