    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...

    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

    Calcium Hypochlorite

    So I decided to mess around with some CH once again,..I used it years ago,..probably around 2004?

    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?

    Titan electric reel sounds like the chain is jumping. 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. Last two seasons I've used the by-pass valve and it worked well. I don't have room for that thing with the new design,..I...

    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...

    Cold Weather Gutter Streaks

    Here's a simple trick some may be able to use for getting gutters white even when it's cold. Add some acetone to your gutter cleaner,..I prefer Purple Power,..but as well as PP works,..when it gets too cold, kinda' just quits. To start,...add 1 quart to 3 quarts PP and simply apply by your...

    Viton Valves / Santoprene Diaphragm and NAOH

    Just wondering how many ounces of NAOH per gallon of water is safe to run with Viton/Santoprene? I hear and read that Viton isn't good for NAOH at 20%. Anyone have experiences with this and could you please tell me what a "safe" NAOH/water mix is for these materials. Thank You, Jeff

    F9 Barc

    I currently use a product for rust removal on concrete, and it works very well. But,..the results aren't immediate, have to wait for the concrete to dry and then it looks great. I've done several concrete driveways that have rust damage from what I assume is from snow plows scraping the...

    Hose Reels

    Wondering how many of you guys running 200' of hose on reels have to pull all the hose from the reel when doing something that requires maybe 100' only? I ask because if I don't pull all the hose off, the hose left on the reel loosens up from the trigger being on/off and makes a big loose mess...

    Surface Cleaner Filter

    Does anyone use a high pressure filter on their surface cleaner? I use one on my rotating nozzle simply due to the ceramic orifice that can be easily damaged by a small particle. Not concerned about damage on the surface cleaner so much,..but it's really irritating when something gets stuck in...
