Hey there, so yesterday i cleaned the valve like i always do every couple months and since putting it back on it is leaking, i put it on correct and no matter what i do it leaks. the leak varies from the sides of the gate valve "box" i guess you would call it to underneath it where the divet is in the pipe. i have a new one on order which i dont know how to install since i didnt install the tank myself. any good advice on replacing the sump valve down pipe or ideas on what to do to stop the leaking? i got the part from marine and reef with expedited shipping. TIA
