Wast Valve Repair
My gray water #1 tank valve on my 5th wheel trailer would not close. I dismantled the valve and found the tank drain pipe blocked with construction debris (plastic shavings, etc. that had built up over the past 4 years). I cleaned it out and reassembled the valve. The valve leaked where it connects to the pipe flanges! I disassembled it again, bought some new rubber seal gaskets (Valterra replacement seals) and put it back together. It still leaks!? I'm wondering if I have the seals in backwards? They are conical shaped. Which way do they go on? Does the wider diameter side face the gate valve blade or does it face the tank side? I used Vaseline to kind of hold the seals in place so they would not get distorted when I bolted the valve to the flanges. I guess they could still have gotten out of place, but I took the valve apart again and they appear to have been in place? That's why I think maybe I put the seals on backwards? I can take it apart again and reverse the seals. However, I thought I would query this forum first and see if anyone can help. Also, is it possible to over tighten the bolts and distort the seals?
