DIY Softwash Metering System


Hello jzbreeland, would you consider selling just the GF 1/2" metering valves? I am looking at rigging up something and like to build stuff myself. Just wondering if you would sell the valves only? Thank you.

If you want to do that, you’d be better off just buying them online yourself honestly.


I have been working on some drawing files for the metering systems to better keep up with parts and to get approximate dimensions for sizing. Here is what I have for the 1" system so far. The left view is fully exploded so that each part can be seen individually. This will help keep track of correct part numbers, and could be sent with systems to help ensure proper assembly, like an instruction sheet. The view on the right is the system all assembled to see what it’ll look like and to get basic measurements.

Note that I don’t have the drawing files for the exact metering valves, so I’ve used generic ball valve that are the right size for the metering valve equivalent.

I plan to update this further to include part numbers and stuff hopefully.


impressive man. looks great!


Here is it with part numbers and descriptions. This is a 1" system with hastelloy check valves. I’ll look at doing the other systems later possibly when I have time to work on it.


Here is the 3/4" system as well. You can see dimensional differences.


Looks awesome! Alright then…bottom line me. How much are you asking for each One? 3/4" and 1"?? Obviously, the 1" system is going to have les flow restrictions, but please give me a quote on each system.


after looking at this i think i’m gonna stick with the 3/4" system. It might not make much sense to use the 1" valve if everything before it is 3/4" (check valve, adapter barb… etc). Or i’m an idiot. i dunno lol.


715$ for the 3/4’ with hastelloy check valves.
915$ for the 1" with hastelloy check valves.

thats not 100% exact but im within 95% of the price. just trying to help @jzbreeland not have to answer every question lol. he’s done enough lol


waut…what? $700, $900?? What happened to $230 something? Wasn’t that the point of this thread…to make a more affordable blending system. I’m confused.


sorry $254.30 - half the price?


I made a couple of mistakes on the previous dimensions. Here is a corrected version. Both the 3/4" and 1" systems come out to the same height, but the width is a little different. This is more accurate. Note that with the 3/4" system, I can’t use street elbows because it has to be reduced to 3/4".

1" System

3/4" System


@cleanunderpressure, you aren’t an idiot. But the hastelloy check valves only come in sizes up to 3/4". But having talked to @tireshark, we think a 1" inlet is too large anyway, so I’d have to reduce the line anyway to 3/4" for the barb. The most restriction comes from the metering valves, not the check valves. The 3/4" check valve should be less restrictive than the 1" metering valve, so I don’t believe it’s an issue. I do believe the 1" metering valve is the better option and I don’t think the 3/4" check valves will hinder flow at all.

@topwash, I’m not using the GF valves. If you read through everything, you’ll see where I posted all the components used in a system along with the MSRP for each part and total material cost for each system. The larger Chemline valves are really expensive. That’s where most of the cost is generated from. I could do the GF valves and build one all 1/2" (and I did build one, there are photos, and @tireshark currently has it for testing and comparing with the 1" system). But once I started researching and learning more about all this stuff, I realized that the 1/2" valves are too small and to build a proper system, larger valves needed to be introduced. And there isn’t a large market for larger metering valves. In fact, Chemline is the only company I’ve been able to identify that makes them. Plastomatic makes a different version, but they quoted me over $400 for a single 1" valve. So that’s not an option.

so your getting a higher flowing proportioner for 2/3 the price and your mad?

what about a system with 2 GF 3/4" valves for the water and bleach and a GF 1/2" valve for the soap. How much would that cost?


Read the thread if you want to know things like this lol. GF doesn’t make the valve larger than 1/2".


what’s this?


How can I PM you?



how did you even get on this website…


Those are standard full port ball valves. I’m pretty sure I made that clear. It was just for size reference.
