Tomorrow, we will be kicking off the spring cleaning season with an early start by cleaning the first home of the season. Unfortunately, we still have a couple of nights in the weather forecast where the temperatures are going to fall below freezing. At this time, I just have the truck parked outside on the driveway so freezing temperatures can have an effect on the window cleaning filters in our truck.  I’m planning on installing the new reverse osmosis membrane we received in the mail the other day. Hopefully, the freezing temperatures over the next couple days don’t damage the new member.  I would prefer to install the new membrane and other filters in 3 to 4 days when the temperatures are much warmer. That said, the new filters have to be installed today so we can clean windows tomorrow and the next day. I will update this blog post below during the reverse osmosis installation process, as well as after I finish installing the new reverse osmosis membrane.

Update: I am currently in the middle of removing the old membrane and replacing it with the new. It looks like this might be an all-day event. I’ve been trying to get this end Off for the last hour!  It turns out that the company that I bought the membrane from was supposed to send me a tool to help me remove the old membrane and replace it with the new. To my disbelief, there was no tool in the packaging. I ended up having to call the company and they recommended another way to remove the caps. The guy that was assigned to help me was pretty funny about it. He made it very clear that the manufacturer does not recommend the method he was about to share with me. He made that abundantly clear! However, he went on to say that a friend of his might recommend filling the housing with so much water,  that the end caps blow right off. Typically, there are you pins in the ends of the tubing to hold the caps in place. That said, if you remove those pins and pressurize the membrane housing, the result is a lot of built-up pressure! He finished giving me that recommendation by saying that he didn’t  recommend that, and it was his friend who might recommend doing so ; )

I went ahead and did what he said, and sure enough one of the end caps blew right off! After that, the replacement of the membrane went fairly smooth. Unfortunately, when the endcap shot off like a rocket, it busted one of the plastic connections that allows us to quick-connect tubing.

As a result, I am making a run up to Lowe’s to replace that plastic piece. After that, Tulsa’s Most beloved window cleaning truck will be ready for some window cleaner action tomorrow. This is going to be a great window cleaning season! The picture at the top of this page is what it looks like when the reverse osmosis membrane and housing are properly installed in the back of the truck. The picture below is what the membrane looks like next to the membrane housing.
