Is this the same thing in thinking of? Ribbed shank and all? Thought Williams did plumbing parts?

why would you need a strap on for a rwp?

 

[Ermintrude]

Some SVP vents are 3" up Norf

Its soil & vent, not RWP.

 

[AWheating]

a downpipe is a rwp in my plumbing speak be it 68,82 or 110. I need a new dictionary

Length, girth or both?

Any way Ermi - How do you know??

Don't answer that....If Croppie wasn't happy with you - we really should leave that between you and him.

Boiler condense? If combined sewer/rainwater

Boiler condense? If combined sewer/rainwater

pointless tho as you need an air break between the two so its best to use a branch and bend.

Seen plenty go straight into downpipe with a blob of silicon.
Whats the air break for, incase the downpipe gets blocked? Most boilers have a condense trap so no smells.

 

[AWheating]

yeah, if drain/rwp blocks with leaves like most have today with this wind. sometimes a hopper is best if room.

 

[stratplus]

So if you were to use a downpipe for a condense you'd use downpipe branch and?

 

[tamz]

A bend then drop your 1/14" or 1 1/2" into it to create an air break.
If you don't have a break and the conductor chokes the boiler will fill with rainwater.
