I have another question. I know it is a lot with all these Larry’s running around.
When I started my thread, I mentioned that we have had no corrosion on the cap/orifice area. Turns out that on the head replacement job we are just finishing up (and unlike the last job we did next door in the same riser system), some of these demo’d heads do have considerable corrosion on the cap and orifice area. Maybe 2-3%. Is that caused by leakage or is more insidious? Thanks.

You can get standard response heads with bulbs that will last another fifty years. Check this head out: https://www.reliablesprinkler.com/sites/default/files/products/bulletins/013.pdf This is an SR bulb head that has it's 1/2" version listed to 250 psi instead of the standard 175. I see that as a nice value added feature for no extra cost, but that's just me.

If we install PRVs, don't need high pressure heads (and probably visa versa), right? 2. Are all high pressure heads the glass bulb type and do bulb type heads require testing every 5 yrs starting with year 20? 3. Are all PRVs flange mounted?

Does anyone know if these sprinklers are actually different from the standard 175psi sprinklers or do they the same sprinklers that have just met a more demanding UL/FM testing protocol?
