TedSchwink Posted September 14, 2015 Report Share Posted September 14, 2015 Escapees Mag. Sept/Oct 2015 issue has article "The Ultimate Water Hose Hookup" : The connection for hose used for black tank flush , and other stuff does not show a pressure regulator. Is a regulator required when flushing the black water tank ? OR just at the City Water connection at the RV. Link to comment Share on other sites More sharing options...
Yarome Posted September 14, 2015 Report Share Posted September 14, 2015 I use a fixed pressure regulator on my black hose, but I haven't really seen that many people who do. I 'really' don't want to knock anything loose in my black tank. Link to comment Share on other sites More sharing options...
Mark and Dale Bruss Posted September 14, 2015 Report Share Posted September 14, 2015 It is not what is in the black tank, it is the hose and pipe fittings connecting the hose connection to the sprayer. I blew the pipe off the sprayer when I put 100 psi park water into the tank rinse, Please click for Emails instead of PM Mark & DaleJoey - 2016 Bounder 33C Tige - 2006 40' Travel SupremeSparky III - 2021 Mustang Mach-e, off the the Road since 2019 Useful HDT Truck, Trailer, and Full-timing Info atwww.dmbruss.com Link to comment Share on other sites More sharing options...
nana25k Posted September 15, 2015 Report Share Posted September 15, 2015 We attach a regulator first.

TedSchwink Posted September 15, 2015 Author Report Share Posted September 15, 2015 Thanks for comments . I also have been using a regulator . The article in the Escapes mag. suggests using a " Y " at site water with disconnects at hose connections to "Y" . As suggested it seams prudent to install the regulator at connection of " y" to site water hyd. Link to comment Share on other sites More sharing options...

socaltoolguy Posted September 16, 2015 Report Share Posted September 16, 2015 Just make sure you have the black tank valve open while flushing so you don't "pressurize" the tank. It would be a bad thing to blow the tank up. Ray 2001 Fleetwood Southwind 32V 2011 Scion XB toad Link to comment Share on other sites More sharing options...

Yarome Posted September 16, 2015 Report Share Posted September 16, 2015 They have to meet someplace, even if you have a hose connected to your neighbors spigot they are meeting. I never attach my black hose to potable water sources. I've seen folks with sewer hookups rinsing and flushing their black tanks while still in their camp spot, but that's just another reason I don't use "city water" at CG's... or frequent CG's really at all for that matter.

Dennis M Posted September 16, 2015 Report Share Posted September 16, 2015 Any factory installed and properly plumbed black tank flush system will employ an air gap fixture that will prevent any back flow from the black tank. Attaching a hose from a potable water source to a black tank flush should create no issue whatsoever. Air Gap Wikipedia On the other hand, sticking your hose into the end of your black tank drain hose to flush it out a real no-no! That's why water bibs at dump stations are labeled non-potable.

Jack Mayer Posted September 16, 2015 Report Share Posted September 16, 2015 You cannot "blow up" a properly functioning black tank. There is an air vent that exits (typically) on the roof. You CAN pump the effluent onto the roof, though, as many people have found out. Jack & Danielle Mayer #60376 Lifetime Member Living on the road since 2000PLEASE no PM's.

TedSchwink Posted September 16, 2015 Author Report Share Posted September 16, 2015 One solution may be to install a hose bib back flow device on "Y" ahead of the black water hose. Link to comment Share on other sites More sharing options...
Jimalberta Posted September 17, 2015 Report Share Posted September 17, 2015 With the air gap fixtures on my MH one for the black and one for the grey there is no back feed to my black hose. I routinely connect the fresh and the black at a Y connector in my wet bay. If I did not have these air gap devices it would be another story. <p>....JIM and LINDA......2001 American Eagle 40 '.towing a GMC Sierra 1500 4X4 with RZR in the rear. 1999 JEEP Cherokee that we tow as well.

Smitty77_7 Posted September 17, 2015 Report Share Posted September 17, 2015 The rinsing of stinky slinky at campsites, is one of the main reasons we carry a spray bottle, mixture of water and bleach, in our plumbing bay. Before attaching our water hose, I first run the water out of the bib for 10-15 seconds. Then scary the hose bib, then attached our hose. I have always been looking for a much water pressure as possible to clean with the grey/black tanks washouts. Good input on too much water pressure can cause a problem, I'll start using a regulator. And note, though I have the same air gap and back flow restrictors already mentioned, I always run the hose bib for another 10-15 seconds upon tank flushing. And, I spray the hose big threads with our bleach before leaving. And I never rinse stinky slinky at a campsite. I will do so sometimes at the dumping station. Final comment on this subject. I always do my best to leave a dumping station better then I found it. It always amazes me to watch how some others will treat this area, and leave it in a disgusting state for the next person behind them. I've seen people use a beat up torn broken hose, with a connection to the coach, and then the ripped end of the hose just laying close to the dump drain. Pardon my french, but crap literally allover and around the area of the drain. Some do rinse with water afterwards, but I've seen others that just drive away with toilet paper clumps all around the drain area. I sometime need to clean a dump area, before even using it. I'm sure I do as the gang here does, always using the proper hose and attachments to do the job as cleanly as possible. If anything ever drips, or spills (Or one time backed up on me.) - I always clean the area the best that I can. The worse that I've seen, was an old rusted banged up duct taped Class C unit - that the owner did not even have hose for. He pulled up close to the dump drain, opened it up, let it drain, then drove off... Not even an attempt to rinse his crap and paper down into the drain... scary!!! Amazing what some feel is acceptable. Best to all, and may your dumping and flushing experiences be as pleasant as possible:)!
