Works well in my RV. keeps up with shower and water use in the kitchen at the same time with good pressure. Was easy to install and did not have any leak problems. I can faintly hear it if everything is quite.

I paired the unit with a 100 watt Renogy Panel and a small EBL Solar Generator and a Gaveenon Instant Propane Water heater and a 12 volt cigarette lighter style extension cord and ran the water line to an adjacent IBC tote to create a shower in the porch. All items except the water tote were purchased on Amazon. Adjacent to it, I put a portable washing machine, also bought on Amazon. The pump is on demand and works strongly to provide for all of my needs. This is my second unit because the first was outdoors and the wiring sheath is made with a soy based plastic that desert rats eat. When I went to replace the wires on the first one, I did NOT realize the unot jad internal spring loaded brushes. I thought it was brushless. So...when I removed the housing, the springs shot off into the sunset across the Sonoran Desert Wilderness! It was morw cost effective to replace it than sourcing springs...a good and solid unit!

Purchased a pump a year prior from a different vendor, and it never shut off when the lines were primed. I messed with fixtures, lines, a test bucket of water with a good attached hose... and that thing would run non stop until turned off at the switch. Turned the allen screw, tightened fittings, etc. It just ran non stop. This pump? As soon as I swapped the old and turned it on... it ran for about 3 seconds and stopped. I ran a faucet, it turned on. I closed a faucet, it turned off. I left it on for a few hours... and it never cycled on until I opened a line... just like it is supposed to. No longevity I can really speak to as I have only had it installed for a weekend trip, but very happy with this one so far. No complaints, at all.

Bought because of the affordable price. Lasted less than a month. I'll be buying a better quality pump to replace this cheap hunk of crap. This company has contacted me and has offered to send a new pump with upgraded pressure switch if I pay for shipping. I informed them I considered that to be VERY poor customer service. Quality companies ship a new pump with a PREPAID return label for the old pump. I'll wait a few days and see how they respond. As of now, I stand by my bad review of this worthless pump. Update......they sent a replacement pump, free and did not want me to return the old pump. I installed the new pump and it worked properly for the 2 days I was at the campsite. As soon as I'm able to go and stay for a longer period of time I will give another update, For now the pump is working properly and the company does stand behind their product. I raised my rating to 4 stars for the good customer service provided by them.

EDIT: Pump has been replaced with a new pump! I have had this pump in my RV since I purchased it 3 months ago to replace an old pump that failed. I know that my water system (other than the pump) is all working properly as it had no issues with the old pump. This pump will do nothing but sputter, work sporadically and and cut in/out. I've tried everything I can think of to fix the issue, which cost me more than this pump is worth. Still doesn't work. I would save yourself a headache and try a different product.

I liked the ease of installation and it wasn't very loud, but I haven't been able to get the pump to shut off without pulling the fuse. The pressure sensor isn't working. I have emailed the company but Janet recieved any answer. So I am looking for an alternative. I didn't get to installing it until 7 months after I purchased it. Not pleased with the customer support or quality at this point. I will update if I hear back from them. Update. The company contacted me and we are trying to work through the issue. They said they would stand behind it. More to come...... Update #2. I was contacted by the company but they didn't follow up with me hardly at all. I ended up buying a shurflo pump that work perfectly out of the box. Very disappointed that youngtree didn't follow up and either refund my money or send me another. I might have just got a bad pump and the product may be good. I don't know. My emails showed blocked the second time I emailed them. If I hear any more I will update this post....... again.
