Calleffi Hydro seperator

Ray Landry_2

I've been using the hydro seperator on my large commercial jobs to avoid p/s what is everyone elses opinion on them? Overpriced? Also, the last two 2 1/2" models I've put in have BOTH had the calleffi supplied 1 1/4 ball valve leak (not cracked) I find it very odd. It appears to be a regualr IPS ball valve, I wicked, and used loctite 565 sealant, so I don't know what the problem is. Also, how many of you guys are using the pro press ball valves? Are they worth the extra money? I usually just use ips and ppxmale adapters to avoid sweating if I'm that lazy, but latley I've been wondering if the install would be more streamline with pp valves.

Caleffi

I wish the Caleffi Hydroseparators were just available now with the sweat connections. They displayed them at ISH in Chicago not to long ago. I have had no problems, but I used a brass nipple and a Fem x PP adapter and have not had any issues.

A few threads down, I have a post with dual Knight boilers and a 1-1/2" hydroseparator.

I also use the propress ballvalves and have not had any secondary issues (cost being primary issue). I am considering the Nibco and Red-White valves just for the sake of value.

I'm an HVAC guy so could you be so kind to explain to me what "wicking and using loctite 565 sealant" method is to stop the leak.

They are methods of thread sealant, like hemp, tape, dope, etc...

Locktite

I dont know about Caleffi's Hydraulic seperators, but I am using Loctite 55 teflon cord more often with thread sealants or loctite sealants.

After using it for the first time i think the only thing it does is make the piping easier but as for air removale i think spriovent work alot faster in removing the air out of the system quicker ,would i use them again it's up in the air but if i did i would also include a spriovent on the system side also i will be adding one to my owmn system after a little re piping .The model i used was ips but with brass union no leals made up quite easy but i have started to have leaks on alot of webstone flanges and am now tring b&g iso flanges abd taco and will have too see keep up the great work ray and never lose sight of your views peace and good luck clammy

Caleffi with ProPress

I just used the Caleffi for the first time and thought it was great. Easy to install and I like the 4 unions a lot – no leak problems, and they are so much cheaper than the Viessmann models. We used ProPress adaptors right off the unit. I do agree that air elimination is better with a Spirovent and will use one in addition next time.
