Rheem SP8346 Temperature and Pressure Relief Valve with 3/4-Inch NPT, Small

Works great! Easy swap out. Quality built and have had no problems with it since installation.

Replaced an old pressure relief valve with this Rheem valve. No probem installation for an older Whirlpool water heater. Corrosion buildup nasty.

Worked perfectly for my Rheem hot water tank.

High quality valve at a better price than the local Builders Supply shipped free to my door.

Was exactly what I needed

Exact product replacement, does not leak like the 11-year old one replaced. Relatively easy installation during a larger effort to replace the magnesium anode rod. This part was as close to trivial as you can get. EDIT: If a new valve leaks, check your water pressure, as you may have a failed pressure reducing valve in the system. It’s a good idea to check line pressure at least twice a year anyway. It’s a very good idea to do that if you are in a hard water area.

The L100XL is supposedly discontinued due to lead content. I had a hard time finding the replacement that the manufacturer suggested. Either the shipping time was way too long, or I thought the price was too high. So I looked for an alternative and found this. The dimensions appeared to match up, so I took a gamble. When I did the replacement, it turns out that the body on this is 1/2" shorter than the body on the L100XL. Luckily it didn't make a difference for the neck clearing my tank. Though the piping I needed to connect it to - for the drain was a bit of a pain to get right because it was 1/2" shorter than I expected. Luckily I was able to make it work. I did some testing and it worked great compared to the old one which was leaking badly at the valve. I was happy with this purchase because I got it at what I felt like was a very reasonable price, as well a fast shipping.

Poor product. Bought in April 2025, started leaking in November 2025.

C’est un bon produit mais j’ai besoin de la couleur bleu les couleurs le petit cap il y a une couleur et ça te dit la pression que tu as de besoin si on installe pas le bon boum est-ce que vous pouvez m’envoyer la bleu svp merci c’est celle là que j’ai de besoin

Parfait

Replaced a similar holder when the tensioner finally wore out. Love the tensioner as it gives the option for one hand usage. Very sturdy.

really good
