A few days ago because our ;ocal water authority is digging up and replacing old sewrage likes in our neighbourhood I decided to buy twelve non return check valves or as I term them stop valves for our air hoses just in case they hit an electric cable and short out the whole area.
I'd been meaning to fit some for 5 years but never got around to buying some.
Their job if people havent heard of them before is to allow airflow to the airstones ut if the air stops they spring shut so that no water is allowed to drain down the air hos into your air pump shorting it out.
If this happens ever to you simply drain the air pump then remove its cover , then turn it upside down and leave it for about a week before putting the lid back on and setting it up again.
If you dont have a spare air pump (we have) then your in trouble so you see the importance of them.
Well this was brought home to me today when I shorted everything and the main breakers clicked off , I'd plugged in a brand new hair dryer we purchased , and "BANG" a spark hot out of the back of it and everything failed.
So you can see the imporance of fitting these valves paying £2.00 each for a peice of mind or as little as $4.00 US
