Ahoy y'all,
The temperature-pressure relief valve on my water heater started leaking regularly and profusely. I removed the old one and found that the local plumbing supply place didn't have anything with a 1/2" thread. I called Seaward, but customer service assured me that I had to call Atwood, since that company had manufactured the unit for Seaward.
Atwood steered me to a local RV dealer, who sold me a Cash Acme NCLX-5. It fits. Atwood technical support assured me that the listed temperature, 210 degrees F., is correct. (She said it might start to weep around 155 degrees--I hope not!)
I'll let you know if this unit causes trouble.
Thanks,
Tony
