Hi,
As I'm plumbing a tank for the first time, I've noticed that many reefers use rigid PVC pipes. Some use flexible pipes, but I rarely see flexible tubing.
Is there any reason why you shouldn't plumb a 1" overflow drain using a male barbed tubing adapter? If I used flexible tubing then I wouldn't have to worry about sloped pipes and elbows to reach the sump.
Something like this but the output would be wider for 1" tubing:
The tubing adapter does narrow down a bit more than PVC pipes. Do you think that would restrict the flow too much?
There is also the possibility of leakage where the flexible tubing attaches to the male adapter, but I've never had a leak in the past when using large diameter flexible tubing. Also, a good set of clamps should seal off the juncture. On the other hand, these tubing adapters are meant for low pressure situations.
Any thoughts are welcomed.
