Here is a picture of an Unloader I have on my Mi-t-m hot water 8gpm Powerwasher. The Pressure switch which won't shut of when The heat is turned on needs to be changed out. If you look at the picture the Pressure switch is on an extra port on this unloader.
I just change the Unloader because it was on the way out. I replaced it with The YU-2140 green spring unloader rated at 21gpm @4500 psi with a 200 degree Temp rating. This Unloader has less ports then the one that was on my Powerwasher. I'm wondering if I set this one up wrong.
First off the Unloader thats on there if you look at the picture on the water out port of the unloader it goes up into the burner. Where it screws in there from the port there is a spring set-up in there. When I put the YU-2140 Unloader in at first I put that spring set-up back in. The problem was the burner was getting no water so I took it out and now the water runs good thru the burner. What is the purpose of that Spring in that connection to the pipe on the coil?
Also with the YU-2140 unloader since it has less ports I put the Burner pressure switch on a TEE up to the Burner because its a pressure switch. Still doesnt shut off when burner is turned on so I think the switch is bad.
Is this an OK spot for the Pressure switch?
I also put a TEE on the bypass where it spills into a tank and also goes back thru the Pump only because the other unloader was set-up like that.
Lastly there is a TEE further up that goes to the coil where there is a hose that goes Nowhere. I'm guess this is in case the pressure builds up in the coil it would go out of this TEE. Problem here is that water is seeping out of this hose. So I'm thinkin that TEE is going bad. Is there a Burst disc in there that might have gone bad?
The pressure on the pump is 2200psi so something is wrong. It could be partly coming from the pump but I'm thinking water coming out of this tee is causing the pressure to drop off.
Any Thoughts would be appreciated.
Thanks
