I'm replumbing my bus tonight and found a couple of ShurFlo valves. What are they? what do they do? and do I need them? I can blow through each end and air comes out but it has a directional arrow on it. I need qualified answers not "I think it is" as I need to get this done tonight. |

Ron,
Usually you only find an arrow on a check valve.
It allows liquid/air/whatever to pass in on direction and not the other.
This may not be what your asking, just throwing it out there.

ShurFlo is a brand name, not a type designation. When u blow thru is there any restriction in either direction, more so than the other. If so, and despite your "positive answer" stance, you could have as most likely possibilities: 1. Pre-set back pressure check valves; 2. Faulty check valves; 3. Flow restrictors. There are a couple more possibilities, but unlikely. The arrow is not necessarily indicative of a check, as it is often used to designate a preferred direction of flow thru the seats of regular gate or globes. So, if u want more positive answers you have to provide more positive information to base those answers on. Hire a UA Union Plumber and quit scabbin' on all the trades (a ha ha). |

ShurFlo is known name for pump but do have small check valve w/spring??? inside to close.
It may be gravity type or greater than "mouth" blow check valve. Another-word higher flow or proper prosition to check (stop).
Or could be dirt in valve to hang open, if so use compress air or city water to blow or flush clean.
Where it hook-up... to inlet of water heater.

I know I am not much help.
Wish you well.

I did hire a union plumber..... He's still on break waiting for the union carpenter who is still on break waiting for the union electrician who is still out looking for a union steward to file a greivance on the union labor who didn't take a long enough break... so I'm doing it myself |

Ron-
HAR!
Well the Plumber's union manual says it's a one-way valve
used for water flow. Air won't be a test for use. You'll have
to pump water through it to make sure it flows through in only
one direction, to insure it's working as it should.
Put it between it and the water tank and the Sureflow pump to
insure the pump doesn't lose it's prime or send bad water
back into the tank while it's not pumping. |

Aye, Aye, Cap: However, a UA Plumber waits on nobody except for the bearer of his paycheck on Friday and that has been known to commence shortly after receiving the last paycheck. Well, I should correct that. I have waited on a back-fill operator or two to make sure they got it covered up before anyone discovered what "corners I had cut". |

My take on this "I've Got A Secret" program is just as you say, just thrown out there.
Unless you know your system, you have to trace back to see what it is intended to isolate.
Valves are used for many uses on buses, the most common is to drain the bus lines.
The arrows are telling me that the flow of water is in the direction of the arrow and if you close the valve, you are isolating that section of piping.
Some really energetic converters will place valves to isolate individual equipment.
To give you much more of an intelligent answer without looking at the system would be very difficult.

Sureflow has its own check valve in the pump to allow "city" water to pressurize the system and NOT backflow into the FW tank.
I would only use an added check valve to keep HOT water from going "back" as the water expands from cold , or on the end of a very long suction line from the FW tank.
It's always nicest to feed the pump by gravity and plumb the pressure side any distance.
1/2 copper tubing works well for delivery , and be sure to use NO clear plastic anywhere light can get to it.

Ron: You call it a Shurflow valve but do you know it is a valve. Shurflow used to make an inline filter for the plastic supply line. You can blow through a filter in both directions. |

Well, in all honesty Ron, without a picture of the "valve" I'd have to think Stan is the one with the right answer... I've seen plenty of Shurflo filters with arrows for flow direction, I can't recall ever seeing a Shurflo valve, check or otherwise.

Me Too!
Only slower still!
Next time I will ask poster if he or she can post a photo of the part or parts.
It would help answer the poster’s question quickly & more accurately.

Well JTNG, that's exactly what my kids say about me, a real pain in the arse you old fool. However, a brand name and an arrow is a vague description. Since I worked with Sure-Flo industrial products many many moons ago and a long time before I ever realized that they had a line of consumer rv products also. I 1st came across them as a flow control metering devices for water treatment chemicals in a/c applications about the same time that the Clarke Cortez was all the rave in the RV world. I think that there consumer rv line grew from that segment of their business, which utilized generally small equipment to meter in drops of this, oz.'s of that. |

Ron-
You coulda' lied and said it looked like the 4th picture down...
Hey... why don't you use it in your act?
James-
Yeah... I have news for ya'. I'm the original reason they invented
Preparation-H.
If a guys says "it looks like this and why would they use it?",
I just assume he knows what it looks like and go from there.
I knew Shurflo made an inline one-way valve about that size
and got a lil' unnerved when someone claimed they don't.
They obviously do.. No harm; no pain.. maybe a round over
my head (again), but so what.. I've been in the barrel before..
It's like "home away from home".
After lurking here for an awful long time (leading up to my
actually doing what most here have done or are doing),
I found that all here have a wealth of knowledge in one
area or another.. and some in -all- areas to a degree.. And
others have some experience that can provide another angle
of an old view..
Neither experience of doing, or by profession, will be correct
100% of the time.... We should all consider ourselves to be
continually on the learning curve. "Experts" fail us too often. |

Well RON, you probably don't want to leave out the strainer.
When I put my shurflo in, da book was so anal about crud getting in the pump that they said to not even use teflon tape on the connections because bits of tape could get in the pump. I did anyway.... |
