Yong Heng.Water does not come out of the return hose

[wbarrett58]

Just unboxed the Yong Heng. Hooked it up and the pump is working but the return hose was at first just dribbling and now nothing comes out of the return hose.I

took the return hose fitting off and no water is returning. Any suggestions ?

If your positive water is being drawn up by the pump then there is a clog in the water passage. Try snaking some pipe cleaners in the passages. You could also try some low pressure (10 to 25 psi) air. Also make sur the pumps is actually pumping water to the height you have the compressor. Those pumps are the cheapest of the cheap and only have a head height of like 12 or 18 inches.

Some of those pump have a togal switch on the bottom.Sucking and none sucking.

Thanks. I blew some air through it and that did the trick. good water flow, ice cold... however trying to top off a 88 cu in tank from 3000 psi the temp hits 60 C in less than a minute.

???

Yeah they get pretty hot. It also depends on where you live also.

It says not to exceed 65 C. Amke sure you have good airflow through the compressor and you might try to add a bit of ice to the water. 
How many gallons of water are you using? More water the slower it will rise. I use about 5 gallons and it still get warm.

Mine was regularly running up to 70c. After doing the following, it stays at about 59c-60c:

The little water pump and bucket should be at approx that same elevation as the compressor. The slide adjuster on the water pump should be set to maximum. Water should enter the compressor on the bottom fitting.

Thats pretty warm pretty quickly. The trick is to remove as much heat as quickly as possible. A extra fan blowing acroos the unit and ice in the bucket are all good ideas. Also check your oil and make sure it is at the proper level. I have heard of people pluming there washing machine cold water line into the water inlet. Hope you get it sorted out quick

They break in hotter 'n heck and slow. give several heat cool down cycles and change that oil quick and often at first and make sure the oil isn't to thin. she'll break in if you're patient. Keep the water full of hunks of ice made from containers. It is worth a little extra hastle for a while with the money you're savin' Bill.

10-4 I'll dump a bucket of ice in the 6 gal bucket tomorrow . My shop is at 75 F due to its with the central air . So we will see what tomorrow brings .

Thanks to all . This Forum rocks .

Definately something wrong there

Something that catches most people out is that the input from the pump goes to the lower brass hose fitting - the upper brass hose fitting is the return to the water container - connecting the hoses wrong will cause over heating quickly

 

[agnthooziast]

Those switches are cheezy also and will quit on you. Get a $15.00 electric motor rated switch from your home store box it and make sure the wire from switch to motor is the same or bigger than the motor wires themselves. Standard oil will eat up seals also as it's dino based.

 

[wbarrett58]

Thanks again to all. I'll try the above and keep truck'n.

After an oil change and several starts and cool downs I got her up to 3800 psi. I thought I was home free and then the burst disc blew. Replaced it . It's 5:00 some where ... I'm going to pour a glass of wine. I did notice a leak on the high pressure head out put side . what do you use on these threads?

 

[prfssrlee]

The fittings usually have a teflon (or other deformable plastic) seal washer that creates the seal - they aren't designed to seal on the threads. Check to see if maybe your output fitting is missing that seal washer or if that seal is damaged. You shouldn't need any thread tape (it can't hurt but it shouldn't help). At first I had a small leak that didn't show up until almost 4000 psi - an extra 1/8th turn on the fitting closed it off and my YH has gone to 4500 psi without issue ever since.

PM me if you need a replacement M10 seal washer as I have a few extra.

OK thanks to all and happy 4 th ... er uh to those on this side of the pond .

I never used the cheesy waterpump that came with mine. I set mine up so the water line hooks to a hose spigot and the other line emptys down a drain. If I want it to run cooler, I just open the spigot more to increase water flow 

My pump runs around 35/36c with this setup

I do have an issue with mine constantly kicking off while I am pumping. It seems to be caused by the crappy switch pictured here:
