Product Details

The Dometic 91604 is a pressure and temperature relief valve designed specifically for RV water heaters. This valve opens at 150 PSI or 210°F, providing critical safety protection for your water heating system by automatically releasing excess pressure or temperature buildup.

Key Features:

  • Factory preset at 150 PSI pressure relief
  • Temperature relief activates at 210°F
  • 1/2" NPT thread connection (male inlet x female outlet)
  • Includes test lever for operational verification
  • Identified by orange plastic thread protector
  • 4" long thermostat probe for installation in hot outlet line

The 1/2" valve was used on all Atwood water heater models manufactured before February 2006. This genuine Dometic replacement part ensures proper safety valve operation and maintains the integrity of your RV's water heating system. Compatible with a wide range of Atwood electronic and pilot model water heaters including GCH6, GH6, G6A, GC10, and many others.

easy to use and easy to pay

Good!

Great prices for the springs I got. Def. the cheapest around! Everything was fast and straight forward.

Ordering was easy

Very good

Did not receive a confirmation email when I placed the order so I was unsure if if the order had gone through properly. Part shipped the day after I ordered it. I received three confirmation emails at the that time for some reason. Overall I would say the experience ordering from Autoplicity was excellent and inspired confidence.

Please send it in the Black color

Glad I found Autoplicity.com. Big potential...<br><br>Ordered parts on Friday, missed 1st delivery attempt to office yesterday (Weds), but received today (Thurs). Little slow on the shipping, but not in a rush for these parts. We typically receive UPS pkgs in 1-2 bus days from Chicago suburbs to Metro Detroit. This took a bit longer, but again - it was not a problem & well worth the savings.<br> <br>Wish web-site would actually separate items for just my car vs all vehicle matches. Finding what I wanted was very difficult, but I'm very pleased with pricing & follow through. I've been back on Autoplicity 2 times now looking for add'tl parts for another vehicle, but have yet to locate them amongst the 100's - even 1000's of results that do not match. If finding them were easier & these add'tl items offer similar savings, I would have spent hundreds more by now. <br><br>If this is a new company, hopefully they can correct the advanced search option as well. Entering a part by vendor name should net results when the brand is listed on the home page & can be found in general queries. Even when I entered the part # for an item it shows no results, but again - searching several dozen pages, I am able to find the same part #. The savings were worth the headache it took to find the brake pads for my BMW, so I won't give up just yet. <br><br>Thanks Autoplicity! Here's to a potentially great future!!
