4\" Propress Fittings

Mike T,

Sorry your having a bad day.

I didn't think my post was as stupid as you obviously did.

We have done up to 2-1/2\" fittings

but have not done 3" or 4" fittings. There shouldn't be any difference between press fitting sizes and time to press each, but I am weighing the time and material of 4" welded fittings and the total net savings was just a bit closer than I expected. (The price of 4" Type L and 4" press fittings will get your attention.)

The project has existing sch40 weld that I will transition to with companion flanges and butterfly valves to a new 4" Caleffi Hydroseparator, then we will create a 4" header with 2" drops for 3 mod/con boilers.

Any sage advice out there, or am I overthinking this?

i'm about to use 3\" pp

tomorrow night on a leaking, main water supply line, and considering the conditions, i most certainly wouldn't want to be soldering it. costly? you bet! but the customer had the option to find someone else to do the 'highwire' act for less $

4\"

We have done 4" wit hout a problem. I recomend cutting the pipe wth a band saw and a wrap around, file the pipe if necessary. Welding pipe can be a pain, you need a welder and a fitter, a fire watch in some areas and it can take alot of time if in a confined space. Have you priced out Victaulic? It may be cost effective especially if you can use a t drill and mechanical tees.

Ditto what Mike said... This job wants Vic.

I don't get involved with pricing anymore at my job. We have done 4" Propress with no problem (other than trying to keep it straight)

If price dosen't matter than propress it is. I would think with the cost of the fittings and copper now that welded and Vic need to be considered.

Ed,

When price doesn't matter anymore - you let us all know.

Okay?

Paul, sounds exactly like my project

Except I am transitioning to 6" black. I went around and around on what material to use...vic, welded, even looked at a product called Corzan (sp?) which is a heat rated cpvc product (only I forgot it had no oxygen barrier). Had to run 120' from new boiler room to existing mechanical room to tie into existing distribution system. While the vic and welded were cheaper for material, in my application I decided on the Propress and 4" L (my cost on the 4" L was $44.00/ft. OUCH!) However, the ease of working with copper and propress finally won out. By-the-by, we have done dozens of jobs totalling literally hundreds and hundreds of 4" Propress fittings. Not a single issue. When you can put together a 4" connection in 7 seconds flat, well, that labor savings goes a LONGGGGGGGGG way to offsetting additional material cost.
We use a DeWalt 12" chop saw with a blade made for cutting non-ferrous metal. Put the chop saw on a flat table and use pipe roller stands to support the rest of the pipe length. After the cut, I take a peanut grinder with a 4" flapper wheel to ream the inside of the pipe with a quick spin around the outer circumference to knock the rough edge off. Then, I take a home-made "plunger" (piece of 3/4" copper pipe with a "swab" taped to the end) to run down the cut length of pipe to remove any shavings. From start of the saw to end of swab is about 1 minute. Lickety-split my friend, lickety-split.


Just my .02 worth,
Rocky
