Anyone know the manufacture of this trap?

Looking to repair

That's an unusual one-is it stuck open or closed?
If stuck open, and unrepairable, you may want to put an orifice on the valve side to limit the amount of steam getting in. Search here for orifices. Pressure must be very low in the range of ounces.
The library here also has info on ancient steam systems.--NBC

I have not been to the home yet. Picture sent from home owner. would like to know more about it before I jump in.

nicholas bonham-carter

Ask him how he knows the trap is bad. Maybe his pressure has jumped up with a lack of regular maintenance-clogged pigtail, etc.--NBC

The call was for banging at a couple of rads. So I asked him to send me a pic of the trap.

Going to head out and scrap off the paint and see what I can find

I zoomed in on that picture and it appears to say VECO on the trap. Here is a link to one thread talking about that type of system.

Vents look to be shot. Settings look to be ok.

The Cut-in on that pressuretrol looks high to me @2PSI. Should be .5PSI. What is the Differential set at? OK, I see there is a Vaporstat on there as well and the settings look OK there. I assume the Pressuretrol is just a backup. It looks like that Pressuretrol/Vaporstat haven't been touched in years and it looks like the pigtail may be steel. That pigtail is probably clogged with gink and needs to be taken off and cleaned. The right seetings on the Vaporstat is worthless if the pigtail is blocked and not sensing the pressure There is more wrong than just the vents. What's causing them to spew water and crud?

DanHolohan

That's not a trap. It's a vapor device. You must run this system on a vaporstat. It's similar to Broomell. Ten ounces should be the highest setting. He's getting hammering because the pressure is too high and steam is passing through the vapor devices into the returns.

Gerry Gill has a video on his web site showing a Mouat Water Seal, which I think is quite similar to this device. I don't know how to post links. His web site is gwgillplumbingandheating.com. Click on the Steam Heating tab, then Vapor Steam Heating, then Mouat Water Seal Return Fitting.

It pays to wander.

I would lower the pressure even more. VECO systems should work at 5 ounces or less. How far away is the furthest radiator in the system? They should also have vents on the return main only. If the vents are leaking steam, then you definitely have steam in the return where it shouldn't be.

Dan I agree it pays to wander. Lots of great info in the Heating Museum.

They have 6 vents on the supply mains in the basement. 3 vents on each main. there is 5 vents on the returns at the boiler.

Mark_72

A lot of venting on this system. almost every rad has a vent or bleeder installed and not one of them should. 25 rads in all. Only one rad has a 17c trap so I 'm impressed that after all these years they still have 24 Veco traps. Going back today to turn it down. Home owner had all 25 rads pulled and taken to be blasted and painted then all re installed. so I was called in because they were leaking at the trap unions and some banging.

Mark_72

Found vents on mains and returns. If this system needs only the returns vented why would someone build antlers and install vents on the mains? The mains are the ones that are spewing .
