Webstone45443WPR 3/4 IPS Lf Iso Exp E3 W/Prv Exp3 Isolation Valves

I have purchased these several times over the years and this product is exactly what is needed for a great tankless installation. All the pieces are very well made. My previous method of installing tankless water heaters was without bleed off valves and it looked like a non pro did the work. This product looks like I actually knew what I was doing. Passes the plumber test !!

worked great and included everything I needed to add the isolation valves, cheaper than I could find anywhere else when including shipping

great price.. worked perfectly with my instant hot water heater..

Great product, so good it's hard to get rapidly!

came as advertized.

The included pressure relief valve is not lead free. The isolation valve body does not react to a 3m instant lead check for a minute of exposure while the pressure relief valve included reacts within seconds turning very red very quickly. This is a strong sign that the lead concentration is very high. Even my lead containing valves in my existing plumbing take longer to react and show a positive result. I did this test twice to double check.This is sold as a "lead free" product when the included parts are not all lead free. This is highly deceptive and I'm trying to remove old lead containing components not add new lead containing ones. With hot water the heavy metal leaching will also be accelerated due to the high temperature and having a hot waster pressure relief valve containing lead right after the hot water output is not desirable.
