A question of filtering poor propane.

I've heard of the goo in natural gas, plumbers recommending a T at each appliance and a drain tube to collect said goo.

Never seen any goo in any of my years of using propane.

The need for propane filtering isn't something I've encountered.

the filter would not work with the goo that forms in propane. the best solution i've found in installing a low point catch for the goo. installing a tee between the flex hose from the regulator to the black pipe going to the r.v.. the tee sometimes needs to be extended if there is a lot of accumulation in the system. i just use a capped fitting on the bottom portion of the tee.
to drain. just turn off the gas. vent the line by turning on a gas appliance for a few seconds. then remove the cap on the bottom of the 'T' that was installed. wipe the oil out of the cap and the tee. re-install the cap and turn on the gas. in places like arizona and new mexico, i found that i needed to drain the tee twice a year. to prevent junk getting into the lines. the regulator has a small filter in the inlet, so if your not getting good pressure, before adjusting the regulator, pull the hose off and check the screen..

Not me, nor have I ever had this issue with any trailer we've owned.
