thats what i figured would happen with the water jet floods are no good we are trying to get rid of the flood not creat one haha, so in a situation like this i can use the spartan 300 in a sink drain, in my recent years of work i have never been in the situation to use it but i was told that if you cant get it with the handy electric do not use the spartan 300 b/c its only used to sewers bc its too powerful
