It is good for a homeowner should intensely focus on drain cleaning of their home about once every three months. This will prevent further damage from clogs.
If you go to the Dentist every 6 months it can be controlled get a deep cleaning that always helps every 2 years
No month has a guaranteed Friday the 13th. Every year does though.
putting a vent on the outside of every drain would block out most debris from going down the drainwithout a vent, the drain could get clogged by misc. thingsin my opinion, drain should have vents, escpecially if you have kidswith the vents, kids won't be able to play and "accidently" shove the plastic t. rex down what they call "the bottomless pit"Waste and soil lines do need a vent .. Storm lines because they do not contain sewer gases do not need a vent Check local codes
Just replace it every 36,000 miles and you will know it is not clogged.
Keeping your washing machine’s drain clear is pretty simple. Clean the lint filter often, and make sure you’re not overloading the machine. Avoid washing clothes with stuff like coins or tissues in the pockets. Adding a drain screen helps catch smaller debris, and it’s a good idea to check the drain hose every now and then to make sure it’s not clogged.
At the least every 6 months. It also depends on how much water your using. Its always best to check them every two months to make sure they are still good.
There should be a new one in May 2012. Usually every 6 months. No, there is always one at thanksgiving (in November), 1 every 12 months :)
To keep your sink clean and clog-free, a cheap alternative to expensive products is to pour boiling water down your sink every few days. If your sink is clogged, try a solution of baking soda, and a few tablespoons of vinegar before rushing out to buy expensive drain cleaners.
Every block has one (L4 or L6) or two (V6 or V8) coolant drains. Not always easy to access.
Once every 12 months, once every 6 months, once every 3 months
