    Filling Another Gap,...Maybe?

    I have been considering something I know others have done in the past,.and I think some still do. Except I'm gonna add a twist to it via my remote unit. I've seen many talk about force feeding a downstream injector to get a stronger concentration,..especially with 8-10 GPM. I never had much...

    Easy Start Valve

    I was looking through old threads and came upon something that led me to something else, Ha,Ha,.. I was noticed some people use easy start valves,.it is a valve that threads into the un-used outlet of the PW pump, sorta acts like a decompression valve acts on a gas engine like bigger chain...

    8 GPM Nozzle with 10 GPM Pump

    I am contemplating switching to 10 GPM this season. I have a rotating nozzle that I use about a handful of times a year, is rated for 8 GPM. Will using this nozzle, or any other nozzle that is a bit smaller hurt the pump in any way? I don't care about the flow loss with the 8 GPM...

    chemical transfer/siphon pump

    This past season I used a 12V 5 GPM Seaflo pump for transferring. I made a wooden box that holds the pump along with it's own battery. (Just a small wheelchair battery is needed) I soldered a plug on the battery and it comes out the back of the box,..and that plug corresponds with one I have...

    10 GPM Through 200' x 3/8" Hose

    As I understand it, running 10 GPM through 200' x 3/8" hose doesn't utilize the full capacity of a 10 GPM pump. My question is this: Are both the flow and PSI restricted or just one or the other? Thanks, Jeff

    Pump setup

    You need lower GPM for applying sealer. more like 1 GPM would suit your needs. And one of those TSC tanks is gonna be a PITA when it comes time to spray another product. How are you gonna rinse it out? If you put your own rig together as a pump and battery and hose, can simply use a...

    Mold From Sunscreen On Resin Chairs

    I did a job (2) years ago on about 100 pieces of pool furniture at a country club. When I looked at it originally,. I seen the mold on the resin chairs and thought it looked odd, big circular blobs of mold,..but still thought is was "just mold",...long story short,..even 12.5% wouldn't...

    Chain Jumping On Titan?

I need to tighten it,..It looks as though the motor bolts are likely slipping in the slots,..So I guess they need loosened and then the motor pushed against to tighten the chain,..and then tighten the bolts. This is fairly rudimentary,..but I...

    12V Hand Held Sprayer

    Thought I'd share a project I've been working on, As you all know,..especially the guys who do other things than roofs,..there is always a need for a small spot sprayer. A pump sprayer works very well to fill that void. Last season I put together a 12V hand truck rig as a gap filler for jobs...

    Scratching my head on EPDM vs VITON with SANTOPRENE Diaphragms

    As I'm delving into the World of 12V pumps for various applications,..I am running into a a couple of questions I keep asking myself. Most of these pumps seem to use VITON or EPDM valves with Santoprene diaphragms? EPDM seems to have a decent rating for a wide range of cleaners that are used...

    Running Two Feeds To Hose Reel

    I made a remote control unit for my soap,..the soap injector is connected to the reel,..But,..I also want to be able to bypass the injector when running a surface cleaner.

    Accumulator Tank

    If running a Delavan 5850 with an accumulator tank and you nozzle down to say 5 GPM, long can it spray without causing an issue? I know nothing about how these work, and am just wondering if they can be sprayed continuously at 5 GPM or if the accumulator gets "caught up" with and then...
