They focus on one specific aspect of the pump in question and don’t address the practical questions I’m asking. No book will say a piston pump shouldn’t be used for this or that, instead, it will only tell you where they are most effective. So the literature I’ve looked into doesn’t seem to have the answers I’m looking for. If you know of books that address this better could you recommend them or do you actually know any? Or have even read any books at all?

My next question is for this site and forum in general. What exactly is your goal here?
When I browse the questions on this forum I see very little helpful advice. Just more of the same journeyman grand standing. You mostly are acting knowledgeable but really you are completely hollow in terms of real advice or help. Every time I try to use this site it’s a big let down. This is not a supportive community of tradesmen teaching and passing on tips but instead a group of back-patters self congratulating each other on how much wiser they are then the people asking questions. This is not a good community for seeking out the experience of people in this trade. So honestly I’m asking. What is the point of this forum? It’s clearly not to encourage and help your fellow tradesmen. So what is it?

For those who have voiced this already thank you. I appreciate the advice about asking other trades. I'll try that for sure.
I'm a new Journeyman and my background is in residential, commercial, and industrial plumbing and pipe fitting. I actually have a wide variety of experience just not a lot of time logged yet as a journeyman.
As for why I don't post often... well I address that in the beginning of the reply. Not a lot of professionals giving advice and instead a lot of journeyman trying to show how important they are.
Remember we live in the age of google. Assume that the people here have already done the google searches and what we're actually looking for here is practical guidance from people who may have already come up against the same dead end in their research.

well its a 2 way street to be honest, you have to be active to get answers and 4 posts in almost 2 years is NOT active..very good advice is given through private messages or in the non public area that you need 300 posts to get to, trade secrets are not going to be openly discussed so the average hack can gain knowledge.
dan holohan has some excellent knowledge and advice, but you also need to be able to understand what he says,

sometimes there is no specific answer on what you ask, but a pump can be used many ways.....
you are also aloud and recommended to give info and join in to be an active member here...sp to pop in once in a blue moon to get some question answered and then you disappear is NOT being part of this forum, so yes you will get your balls broken till you prove who you are and that you are willing to do your share of an active member....

For us members there isn't a "point" to this forum, we do it for entertainment. For some entertainment can mean learnin and helping other learn, for others it's taking out pent up aggression. As such you will get answers based on how that individual feels that day about you and whether or not you warrant an answer in their mind.



For the site owner the "point" of the system is to make money.



To answer your questions;



The high pressure testing pump could create too much pressure and blow the system if you aren't careful.


Yes, a ciculator pump is USAULLY a normal centrifugal pump, some are designed a little differently. Basically flow and pressure graph inversely. If you want efficiency then you should get a circulator that produces just enough head to do the job, otherwise the impeller will constantly be encountering more fluid resistance and will have less flow.


Circulators should have valves on either side for ease of maintenance. I did have one old manager who felt they shouldn't just so it would be more difficult to service and the customer would be more likely to call us and if they called someone else they would be more likely to turn the customer down so we didn't lose that customer or at least that service call. No valves means draining the whole system and thus a lot more time. It also means a slightly lower install cost so your bid has a better dollar amount.

Correct on this site being a 2 way street.

I'm lazy, even 34 years in the business and I still call a local rep or the manufacturer tech support. Especially pumps.

I agree, same guys here with major attitudes. I have come here twice and been attacked both times. Master plumber and cross conncetion control tester with 25 years experience. The field is too large for one person to know it all.

well it may be the same people, im not ruling myself out either, but most of it is friendly banter to get to know how some one ticks...8 posts in almost 4 years I know nothing about you or how you roll, and being an active part of a forum requires one to be involved, not with just asking questions but posting jokes and stuff about you on the outside of plumbing..
the people that just show up on the doorstep looking for advice with very minimal posts or interaction is met with some ball busting, and those that bust back and banter earn the respect and also prove they are part of the trade and not some hack that can say anything they want in a few posts...
so maybe this explains why you got the responses in the past...and being in the trades one must have a thicker skin than most to put up with the ribbing they get...
understand it is friendly in the end to see if you are who you say you are, and if you get offended that fast and give up..well thats who you are, if you stick it out then you are most welcome and info will be shared freely...
if you were active you would see the people here with large post counts break each others balls almost as much as the new guy, but with your measly 8 posts in almost 4 years I doubt you would see much...and only come around for a quick answer and then disappear..
im not saying you need to be a daily poster but once a month would be nice and that would give you around 50 posts, hopefully you would see this is a fun place and visit and post more often..thats what will keep the forum growing, but not with 1 question willies showing up twice a year...

ps I went back and read all 8 of your posts, you were given amble help and information, but it seemed like you were too lazy to read the material given to you to learn what you needed and not spoon fed the info like a child,

having a brain also needs it to be used, and if your in the trade reading and understanding the material is crucial for you to move on in this trade..
so why dont you become active and see the difference,,
thats what pisses off most of the active people are the newbies with an attitude of entitlement right off the start..
when you start a new job do you expect 2 hour lunches like the bosses and top pay??

typical short poster, just come by and complain, I guess the truth hurts, see you in a few years for your next post complaining about something...

Hi everyone! I’m working more and more around pumps these days and it seems like I keep getting conflicting information about how to use them depending on who I talk to. It feels like the journeymen I work with all have different rules around pumps, which ones need priming, and when and where you can use them. I’m looking for advice, or maybe some books to read, or resources to seek out, even courses to take, so that I can get good solid information about all the kinds of pumps we work with. Here are a couple of examples:

1.When I wanted to pump a bucket of glycol into an empty pipe system made of 6 inch steel all I had to use was a piston pump. It was rated for 2.2 gpm and had a max psi of 500. I know it’s used as a booster pump to raise system pressures for testing but I figured I could pump a bucket with it. It would be slow compared to a centrifical pump but I thought it would still work. I was reprimanded by a journeyman who told me that piston pumps are only for transferring liquids into full systems. Is this true? Also no one primes the piston pump but I thought they needed priming regardless unless designed as “self priming.” Is this true? Or are all piston pumps self priming?

2.A coworker thought the impeller of a circulation pump wasn’t working or at least not producing flow. The motor looked like it was turning. It’s a mounted portable unit used for cleaning systems before glycol goes in. I thought we could prove that the impeller was working by simply pulling water out of a bucket and into another with the circulator so that we could see the flow. A third journeyman showed up and basically called me stupid. Basically he said that circulators don’t pump. They just sit in line with a system and push water around. I tried to explain that it’s still a centrifical pump but simply low powered compared to what you would use to transfer fluids or boost pressure. I felt that even a circulator will still draw water from a bucket as long as it’s primed and not being forced to lift very high. Am I stupid or was the journeyman wrong about circulators?
"A circulator pump or circulating pump is a specific type of pump used to circulate gases, liquids, or slurries in a closed circuit. They are commonly found circulating water in a hydronic heating or cooling system. ... Circulator pumps as used in hydronic systems are usually electrically powered centrifugal pumps."

They have performance curves showing their pumping characteristics just like any other centrifugal PUMP.

When you have a question on specific equipment, the best way to get a good answer is call the manufacturers.

I won't touch the first question because I don't want to get into a debate.
EDIT: Sorry...I didn't see and read all the responses before I posted my comments.

EDIT2: Just read the rules for membership. requires active professional. I'm a RETIRED plumbing engineer. So long!
