Two inch PVC suction nozzle 

Really useful especially in our place where ready to use nozzles are rarer than gold. Thank you!

This is absolutely fantastic!! I met guy up in Maine working the river with your prototype. It worked flawlessly!!!! I will be building one tomorrow. Thanks for the insight🤘⚒️

I'm not sure this is very cost effective considering time and material when you can buy a steel nozzle for $100. But this is an excellent video for the diy guys.

This is so wrong the pressure water has to be introduced immediately after the suction side of nozzle or pressure water will be pushed out of the suction side. I am a mechanical engineer and your design goes against physics sorry😢

That has alot of suction. You really seem to know what your doing. I am currently attempting to build a 4 inch nozzle in order to suck sand off a lake bed and pump it behind a new seawall for backfill. I am attempting to pump the sand up to 6' in height. So far I have been able to pump sand but not enough. I dont have good suction. I am running a riverside 2-1\2" high pressure pump powered by an 11hp honda engine. What should my jet size be for my 4 inch system? Do you have any suggestions?

Where's the venturi? 🤔

muy Bueno......gracias!!!!!!!!!!!!!!!!!!!!!

for a ultimate aderance with a pvc pipe wash interior pipe witch thinner and after sand 180 ans re wash take a carton for mix and stay in your box tool for a next time is more gravely ...sanding... more batch more sanding he falling love in a body shop i work ... sorry for my english im stay in quebec city.......and for your bubble take a old electric sanding put your piece witchputty wen on in a pad the vibration make a job see a next tine ....jim ...famille jim594 at g mail

Nice work. But how many hp is of your motor pump? Can I do dredging of a pond with 2 hp motor and this nozzle? If not what should be the min capacity?

well its nice use of my principle :) that i use in my nozzle i made :)

the best friend at the putty are a thinner with clothes ....hihihihhi not yours finger ...hhiihihihi

Great idea, but bondo absorbs water. Use a fibreglass reinforced filler instead

This is the BEST EXPLANATION of a dredge I have seen on utube. You are a star. Are you using a 12v pump or gasoline?

Nice build I couldn't do it better myself :)

Parabéns ! Gostei muito . Tenho uma saída da motobomba de pressão a gasolina de 2" polegadas ,,,, esta pasta que você coloca é uma cola ? E onde posso encontrar para comprar ? Obrigado desde já . Parabéns pelo talento e a forma clara de explicar .Att.

Enjoyed the vid, does the "u" piece serve any purpose?

The "u" piece is to get the high pressure water to the jet.

I am dredging a hole in my boat slip and saw your video and said this may work. My question I am curious about is that if I use a 4 or 5 foot gravel (in my case sand)suction pipe would that affect the performance? I need to move about 3 yards of sand for my keel to rest in. Thanks for share your video.

,hi Randal,,will a 50 cc honda work,,my keen nozzle scree up,nice work

Nice idea Thanks for sharing, sO the size of the inner hole is 1/2 inch correct?

Great idea!

Would I need to make some diameter adjustments if I wanted to use a 3000gph 12v bilge pump?

Хорошо придумано. Спасибо
