Hey guys newbie here been doing oil for about a month and was wondering what the best way to change a strainer on a 2 pipe system, I was told to take the pump off the burner and do it quickly over a bucket if any one has any more efficient ways I'd appreciate hearing them

    If the return line runs to the bottom of the tank oil may sylphon back through the return. That's why I always put a check valve on the return regardless of any incoming flack.

    So that's the choice. Over a bucket could get messy every time. Putting in a check will be messy once, and maybe not at all if you can cut into the return up high

    Flack!...lol
    First, does it have to be 2 pipe?
    It depends on how the pipes relate to the tank. If it's a total lift job you should get almost no oil when you crack the strainer.
    I usually fix the oil lines if at all possible to make it easier in the future. It's nice if they don't 90° under the strainer, but either drop 4" or 5" first, or come down and 90° under the burner housing. Not always possible obviously.
    Then I took a little piece of sheet metal (be careful on flex lines) and notched it out, with a little lip on the 'back'. I can slip it between the two port under the pump to channel the oil over the lines and into my little container to catch the oil. I put a rag under the sheet metal to hold it in place and catch anything that may try to get thru. A little magnet in the right spot on the back helps it stick to the motor.

    Check valve sounds easier & I like 2 pipe anyhow!!!

    Personally I get rid of the 2 pipe and install a tiger loop w a spin of gar filter throw on a vacuum gauge and your done . There’s nothing worse then filtering 18 gpm and your burning 1 gpm and any issues w a leak on the return and your leaking oil some where and if it’s a older tank then every oil delivery-is the standard filter nozzle and strainer and burner head cleaning for get about it ? . In Europe and else where tiger loops are the standard and 2 pipe to the tank is old school and not done due to possible Enviromental issues and issues w flame retention burns and vacuume. There’s nothing nicer then a oil pump not pulling any vacuume and running as should be some thing that when a return line is particularly clogged and there’s vacuumed being pulled is not going to happen . I always felt that you should give a oil burner the respect it deserves and all the best chances to operate at the best it can and properly .Remenber a clogged return over time will kill a pumps seal and cause a leak . In this day and age w all the goodies new burners are equipped w delayed ignition ,pre and post purge oil delay valve and so on if installing a new boiler or burner and a tiger loop and spin on is not installed it’s shame on you and stop cheating your customers and do it right first time out . Peace and good luck clammy
